Question

What is the slope of the line through (-10, 1) and (0, -4)?

Answer 1

Correct Answer: The slope would be -0.5.

Explanation:

You have to find the change in the y-coordinate and divide it by the change in the x-coordinate.

So it would be (1 - (-4)) = 5 for the change in Y. And it would be (-10 - 0) = -10 for the change in X. So the final slope would be 5 divided by -10, which would result in -0.5.

Answer 2

-1/2

Explanation:

The slope can be found by

m = (y2-y1)/(x2-x1)

= (-4-1)/(0 - - 10)

(-4-1)/(0+10)

-5/10

-1/2
