Question

How do you find the slope of the line that passes through (8,-2), (1,1)?

Answer 1

`-3/7`

Explanation:

First, find the slope. Let `x_1=8`, `x_2=1`, `y_1=-2`, and `y_2=1`.
Then substituting these numbers into the slope formula, we get...
`m=(y_1-y_2)/(x_1-x_2)`

`m=(-2-1)/(8-1)`

`m=(-3)/(7)=-3/7`

So our slope, designated by `m`, is `-3/7`.
