To find the slope-intercept form of the equation, we need to solve for y.
8x + 5y = 15
5y = -8x + 15
y = (-8/5)x + 15/5
y = (-8/5)x + 3
The equation is now in slope-intercept form, y = mx + b, where m is the slope and b is the y-intercept.
The slope is -8/5 and the y-intercept is 3.
Since there is only one value for the y-intercept, there are no infinite solutions.

find the slope intercept and the y intercept that has infinite solutions to the equation.
-24x+2y=46
-24x+2y=46
To find the slope-intercept form of the equation, we need to solve for y.
-24x + 2y = 46
2y = 24x + 46
y = (24/2)x + 46/2
y = 12x + 23
The equation is now in slope-intercept form, y = mx + b, where m is the slope and b is the y-intercept.
The slope is 12 and the y-intercept is 23.
To have infinite solutions, the given equation needs to be equivalent to another equation in slope-intercept form with the same slope and y-intercept.
However, the slope-intercept form of the equation clearly has only one unique slope (12) and y-intercept (23), so there are no infinite solutions.
-24x + 2y = 46
2y = 24x + 46
y = (24/2)x + 46/2
y = 12x + 23
The equation is now in slope-intercept form, y = mx + b, where m is the slope and b is the y-intercept.
The slope is 12 and the y-intercept is 23.
To have infinite solutions, the given equation needs to be equivalent to another equation in slope-intercept form with the same slope and y-intercept.
However, the slope-intercept form of the equation clearly has only one unique slope (12) and y-intercept (23), so there are no infinite solutions.
solve the following inequality.
-2/4y is less than or equal to 4
y is greater than or equal to ?
-2/4y is less than or equal to 4
y is greater than or equal to ?
To solve the inequality, multiply both sides of the inequality by 4 to eliminate the fraction.
(-2/4y) * 4 ≤ 4 * 4
-2y ≤ 16
Next, divide both sides of the inequality by -2, remembering that when you divide by a negative number, you must reverse the inequality sign.
(-2y) / -2 ≥ 16 / -2
y ≥ -8
So, the solution to the inequality is y ≥ -8.
(-2/4y) * 4 ≤ 4 * 4
-2y ≤ 16
Next, divide both sides of the inequality by -2, remembering that when you divide by a negative number, you must reverse the inequality sign.
(-2y) / -2 ≥ 16 / -2
y ≥ -8
So, the solution to the inequality is y ≥ -8.
solve the following inequality
-5(-10x+8) less than or equal to 3
x is less than or equal to ?
-5(-10x+8) less than or equal to 3
x is less than or equal to ?
To solve the inequality, first simplify the expression inside the parentheses by distributing the -5:
-5(-10x + 8) ≤ 3
50x - 40 ≤ 3
Next, add 40 to both sides of the inequality to isolate the x term:
50x - 40 + 40 ≤ 3 + 40
50x ≤ 43
Finally, divide both sides of the inequality by 50 to solve for x:
(50x) / 50 ≤ 43 / 50
x ≤ 43/50
So, the solution to the inequality is x ≤ 43/50.
-5(-10x + 8) ≤ 3
50x - 40 ≤ 3
Next, add 40 to both sides of the inequality to isolate the x term:
50x - 40 + 40 ≤ 3 + 40
50x ≤ 43
Finally, divide both sides of the inequality by 50 to solve for x:
(50x) / 50 ≤ 43 / 50
x ≤ 43/50
So, the solution to the inequality is x ≤ 43/50.

-10y,30
y>?
10z<-30
z<?
10x<30
x<?
-10y,30
y>?
10z<-30
z<?
To solve the inequality 10x < 30, divide both sides of the inequality by 10:
x < 3
So, the solution to the inequality is x < 3.
To solve the inequality -10y < 30, divide both sides of the inequality by -10. Remember to reverse the inequality sign when dividing by a negative number:
y > -3
So, the solution to the inequality is y > -3.
To solve the inequality 10z < -30, divide both sides of the inequality by 10:
z < -3
So, the solution to the inequality is z < -3.
x < 3
So, the solution to the inequality is x < 3.
To solve the inequality -10y < 30, divide both sides of the inequality by -10. Remember to reverse the inequality sign when dividing by a negative number:
y > -3
So, the solution to the inequality is y > -3.
To solve the inequality 10z < -30, divide both sides of the inequality by 10:
z < -3
So, the solution to the inequality is z < -3.
graph and then find the solution for y=1/2x+2 and y=-1/4x+8
To graph the equations y = (1/2)x + 2 and y = (-1/4)x + 8, we can plot points on a graph and connect them to form the lines.
For the equation y = (1/2)x + 2:
Let's choose a few x-values and substitute them into the equation to find the corresponding y-values:
When x = 0, y = (1/2)(0) + 2 = 2
When x = 2, y = (1/2)(2) + 2 = 3
When x = -2, y = (1/2)(-2) + 2 = 1
Plotting these points, we get:
(0, 2)
(2, 3)
(-2, 1)
Next, let's do the same for the equation y = (-1/4)x + 8:
When x = 0, y = (-1/4)(0) + 8 = 8
When x = 4, y = (-1/4)(4) + 8 = 7
When x = -4, y = (-1/4)(-4) + 8 = 9
Plotting these points, we get:
(0, 8)
(4, 7)
(-4, 9)
Now, we can connect these points to form the lines:
The line for y = (1/2)x + 2 is a straight line that rises as x increases, passing through the points (0, 2), (2, 3), and (-2, 1).
The line for y = (-1/4)x + 8 is a straight line that falls as x increases, passing through the points (0, 8), (4, 7), and (-4, 9).
