Question

What is the slope of the line that contains the points (1,-1) and (-2, 8)?

Answer 1

The slope is `-3`.

Explanation:

To find the slope given two points, we use the formula `"rise"/"run"`, or `(y_2-y_1)/(x_2-x_1)`.

Plug in the given points into the formula:
`(8-(-1))/(-2-1) = 9/-3 = -3`

Therefore, the slope is `-3`.

Hope this helps!
