Analyze the linear function whose slope is -3 and passes through the coordinate pair (-2,0). Which linear function matches this line?

7 answers

The linear function that matches a slope of -3 and passes through the coordinate pair (-2,0) can be found using the point-slope form of a linear equation.

Point-slope form: y - y₁ = m(x - x₁)

m is the slope of the line, and (x₁, y₁) is a point through which the line passes.

Using the given values, the equation becomes:

y - 0 = -3(x - (-2))

Simplifying:

y = -3(x + 2)

Expanding the brackets:

y = -3x - 6

Therefore, the linear function that matches this line is y = -3x - 6.
woops, the pair meant to be (2,9) not (2,0) my bad can you try again?
No problem! Let's recalculate the linear function using the correct coordinate pair.

Using the point-slope form of a linear equation:

y - y₁ = m(x - x₁)

For this new coordinate pair (2,9) and a slope of -3, the equation becomes:

y - 9 = -3(x - 2)

Expanding the brackets:

y - 9 = -3x + 6

Adding 9 to both sides:

y = -3x + 15

Therefore, the linear function that matches the line with a slope of -3 and passes through the coordinate pair (2,9) is y = -3x + 15.
none of those matched the 4 options, so here they are so u can decide the right one
A. y=-2x-3
B. y=-3x+3
C. y=3x-3
D. y=-3x+9
Apologies for the confusion. Let's determine the correct linear function again.

Using the given slope of -3 and the correct coordinate pair (2,9), the equation becomes:

y - y₁ = m(x - x₁)
y - 9 = -3(x - 2)

Expanding the brackets:
y - 9 = -3x + 6

Adding 9 to both sides:
y = -3x + 15

Comparing this equation with the options provided, we find that the correct linear function is:

D. y = -3x + 9

To find the linear function that matches a slope of -3 and passes through the coordinate pair (-2,9), let's use the point-slope form of a linear equation:

y - y₁ = m(x - x₁)

Substituting the values, we get:

y - 9 = -3(x - (-2))

Simplifying the equation:

y - 9 = -3(x + 2)

Expanding the brackets:

y - 9 = -3x - 6

Adding 9 to both sides:

y = -3x + 3

Therefore, the linear function that matches this line is:

B. y = -3x + 3
