what is the slope of the linear function y= -2x + 3
Bot
The slope of the linear function y= -2x + 3 is -2. In general, the slope of a linear function in the form y=mx+b is equal to the coefficient m of the x-term. In this case, the coefficient of the x-term is -2, so the slope is -2.
bott
can you graph a slope of -2
Bot
Yes, I can help you graph a slope of -2! To graph a line with a slope of -2, you need to plot at least two points on the coordinate plane. Here are the steps to graph a line with a slope of -2:
1. Choose a point to be the y-intercept. The y-intercept is the point at which the line crosses the y-axis, so its x-coordinate is 0. Let's choose the y-intercept to be (0, 5).
2. Use the slope to find another point on the line. The slope is equal to the change in y divided by the change in x between any two points on the line. Since the slope is -2, this means that for every increase of 1 in the x-coordinate, the y-coordinate decreases by 2. To find another point, we can start at the y-intercept (0, 5) and use the slope to find another point. If we increase the x-coordinate by 1 to get to x=1, then the y-coordinate should decrease by 2 to get to y=3. So another point on the line is (1, 3).
3. Plot the two points you found (the y-intercept and the other point) and draw a line through them. Your graph should look like a straight line that slopes downward from left to right.

given the function rule f(x)= x^2 - 3x + 2, what is the output of f(-2)
Bot
To find the output of f(-2), we need to substitute -2 in place of x in the function rule f(x) and solve for f(-2). That is:
f(-2) = (-2)^2 - 3(-2) + 2
Simplifying this expression, we get:
f(-2) = 4 + 6 + 2
f(-2) = 12
Therefore, the output of f(-2) is 12.
f(-2) = (-2)^2 - 3(-2) + 2
Simplifying this expression, we get:
f(-2) = 4 + 6 + 2
f(-2) = 12
Therefore, the output of f(-2) is 12.

can you graph linear function y= -2x + 3
Bot
Yes, I'd be happy to help you graph the linear function y = -2x + 3!
To graph a linear function, you need to plot two points on the coordinate plane and then draw a straight line through them. You can do this in a few easy steps:
1. Start by finding the y-intercept, which is the point where the line crosses the y-axis. In this case, the y-intercept is 3, since the equation is in the form y = mx + b, where b is the y-intercept.
2. Choose a value for x and use the equation to find the corresponding value for y. For example, if we choose x = 0, we know that y = -2(0) + 3 = 3, so one point on the line is (0, 3).
3. Choose another value for x and find the corresponding value for y. If we choose x = 1, we know that y = -2(1) + 3 = 1, so another point on the line is (1, 1).
4. Plot the two points (0, 3) and (1, 1) on the coordinate plane, and then draw a straight line through them.

draw a table for function rule y=4+5x
Bot
Sure, here's a table for the function rule y = 4 + 5x:
| x | y |
|-------|-------|
| -2 | -6 |
| -1 | -1 |
| 0 | 4 |
| 1 | 9 |
| 2 | 14 |
To create this table, you simply need to choose different values for x and then plug them into the equation to find the corresponding values for y. For example, when x is -2, we have:
y = 4 + 5(-2) = -6
So the first row of the table is (-2, -6). We repeat this process for the other values of x, and we get the complete table as shown above.

what about x 3 and x 4 in the table
Bot
Sure, I can add x=3 and x=4 to the table:
| x | y |
|-------|-------|
| -2 | -6 |
| -1 | -1 |
| 0 | 4 |
| 1 | 9 |
| 2 | 14 |
| 3 | 19 |
| 4 | 24 |
To find the corresponding values of y when x is 3 or 4, we simply plug those values into the equation y = 4 + 5x.
For x = 3, we have:
y = 4 + 5(3)
y = 4 + 15
y = 19
Therefore, when x=3, y=19.
For x = 4, we have:
y = 4 + 5(4)
y = 4 + 20
y = 24
Therefore, when x=4, y=24.
I hope this helps!

it did. The sale price of shrimp at a local grocery store is $1.15 for the first ounce and $0.95 for each additional ounce. write a function rule for that.
Bot
Sure! Let's call the total cost of the shrimp C and the number of ounces of shrimp purchased x.
For the first ounce of shrimp, the cost is $1.15. For each additional ounce, the cost is $0.95. Therefore, we can set up the function rule as follows:
- For x = 1 (1 ounce of shrimp): C = 1.15
- For x > 1 (more than 1 ounce of shrimp): C = 1.15 + 0.95(x-1)
In words, the function rule for the cost of shrimp is:
- If you purchase one ounce of shrimp, it will cost $1.15.
- If you purchase more than one ounce of shrimp, the cost will be $1.15 plus $0.95 for each additional ounce after the first one.
I hope this helps!

Which function rule shows how the cost of shrimp, y, depends on the number of ounces, x.
Bot
The function rule that shows how the cost of shrimp, y, depends on the number of ounces, x, is:
- For x = 1 (1 ounce of shrimp): y = 1.15
- For x > 1 (more than 1 ounce of shrimp): y = 1.15 + 0.95(x-1)
In words, this function rule states that the cost of shrimp y will depend on the number of ounces x purchased. For one ounce of shrimp, the cost will be $1.15. For any additional ounces beyond the first one, the cost will be $0.95 for each additional ounce, plus the initial cost of $1.15.
- For x = 1 (1 ounce of shrimp): y = 1.15
- For x > 1 (more than 1 ounce of shrimp): y = 1.15 + 0.95(x-1)
In words, this function rule states that the cost of shrimp y will depend on the number of ounces x purchased. For one ounce of shrimp, the cost will be $1.15. For any additional ounces beyond the first one, the cost will be $0.95 for each additional ounce, plus the initial cost of $1.15.
bott
would y=0.95(x-1) + 1.15 be the same as y= 1.15+0.95 (x-1)
Bot
Yes, both function rules are equivalent.
The order of addition and multiplication does not affect the final result, so we can rearrange the terms in the equation y = 0.95(x-1) + 1.15 as follows:
y = 0.95x - 0.95 + 1.15
y = 0.95x + 0.2
This is equivalent to y = 1.15 + 0.95(x-1), which we can simplify as:
y = 0.95x - 0.95 + 1.15
y = 0.95x + 0.2
Both functions represent the same relationship between the number of ounces of shrimp purchased and the cost of the shrimp.

This is equivalent to y = 1.15 + 0.95(x-1), which we can simplify as:
y = 0.95x - 0.95 + 1.15
y = 0.95x + 0.2
Both functions represent the same relationship between the number of ounces of shrimp purchased and the cost of the shrimp.

| -2 | 2 |
| -1 | 5 |

To create the table, you simply need to substitute different values of x into the equation y=3x+8 and then evaluate the expression to get the corresponding value of y. For example, when x is -3, we have:
y = 3(-3) + 8
y = -9 + 8
y = -1
So the first row of the table is (-3, -1). We repeat this process for the other values of x, and we get the complete table as shown above.

write a function rule for if x=-3 and y=-1, x=-2 and y=2, and x=-1 and y=5
Bot
Sure! We can use the three given points to find the function rule for a linear equation using point-slope form as follows:
- First, we can find the slope of the line passing through the given points using the formula:
m = (y2 - y1) / (x2 - x1)
Plugging in the given points, we get:
m = (5 - (-1)) / (-1 - (-3))
m = 6 / 2
m = 3
- Next, we can use the point-slope form for a linear equation:
y - y1 = m(x - x1)
Plugging in one of the given points and the slope we just found, we can choose (x1, y1) = (-1, 5) to get:
y - 5 = 3(x - (-1))
y - 5 = 3(x + 1)
- Finally, we can simplify the equation to get it in slope-intercept form:
y - 5 = 3x + 3
y = 3x + 8
Therefore, the function rule for the linear equation that passes through the three given points is y = 3x + 8.
- First, we can find the slope of the line passing through the given points using the formula:
m = (y2 - y1) / (x2 - x1)
Plugging in the given points, we get:
m = (5 - (-1)) / (-1 - (-3))
m = 6 / 2
m = 3
- Next, we can use the point-slope form for a linear equation:
y - y1 = m(x - x1)
Plugging in one of the given points and the slope we just found, we can choose (x1, y1) = (-1, 5) to get:
y - 5 = 3(x - (-1))
y - 5 = 3(x + 1)
- Finally, we can simplify the equation to get it in slope-intercept form:
y - 5 = 3x + 3
y = 3x + 8
Therefore, the function rule for the linear equation that passes through the three given points is y = 3x + 8.

write a function rule for if x=0 and y=2, and x=2 and y=1, and x=4 and y=0, and x=6 and y=-1.
Bot
Sure! We can use the four given points to find the function rule for a quadratic equation using standard form as follows:
- First, we can use the three given points to set up a system of equations and solve for the coefficients of the quadratic equation. Let's choose the standard form of a quadratic equation y = ax^2 + bx + c.
When x = 0, y = 2, we have:
2 = a(0)^2 + b(0) + c
2 = c
When x = 2, y = 1, we have:
1 = a(2)^2 + b(2) + c
1 = 4a + 2b + 2
When x = 4, y = 0, we have:
0 = a(4)^2 + b(4) + c
0 = 16a + 4b + 2
When x = 6, y = -1, we have:
-1 = a(6)^2 + b(6) + c
-1 = 36a + 6b + 2
Solving this system of equations, we get:
a = -0.25, b = 1.25, c = 2
- Finally, we can write the function rule in standard form:
y = -0.25x^2 + 1.25x + 2
Therefore, the function rule for the quadratic equation that passes through the four given points is y = -0.25x^2 + 1.25x + 2.
- First, we can use the three given points to set up a system of equations and solve for the coefficients of the quadratic equation. Let's choose the standard form of a quadratic equation y = ax^2 + bx + c.
When x = 0, y = 2, we have:
2 = a(0)^2 + b(0) + c
2 = c
When x = 2, y = 1, we have:
1 = a(2)^2 + b(2) + c
1 = 4a + 2b + 2
When x = 4, y = 0, we have:
0 = a(4)^2 + b(4) + c
0 = 16a + 4b + 2
When x = 6, y = -1, we have:
-1 = a(6)^2 + b(6) + c
-1 = 36a + 6b + 2
Solving this system of equations, we get:
a = -0.25, b = 1.25, c = 2
- Finally, we can write the function rule in standard form:
y = -0.25x^2 + 1.25x + 2
