Question

What is the slope of (-2,4) and (2,-1)?

Answer 1

`-5/4`

Explanation:

Use the slope fomula:

`m=(y_2-y_1)/(x_2-x_1)`

You do the second `y_2` (which is `-1`) minus the first `y_1` (which is `4`), over the second `x_2` (which is `2`) minus the first `x` (which is `-2`).

`(-1 - 4)/(2 - (-2))`

Then you solve the top and bottom and are left with

`-5/4`

Which is your slope
