Question

How do you find the slope for (1,6) & (-1,-2)?

Answer 1

`m=4`

Explanation:

Use this formula to find the slope where `m` is the slope

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

This formula makes sense because slope is rise over run. Rise being the `y` values and run being the `x` values.

Now you choose which point is point 2 (includes `y_2` and `x_2`) and which point is point 1 (includes `y_1` and `x_1`)

Point 2: `(1,6)->y_2 = 6` and `x_2 =1`
Point 1: `(-1,-2)->y_1 = -2` and `x_1 = -1`

Plug into the formula and solve for the slope:

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

`m=(6-(-2))/(1-(-1))`

`m=(6+2)/(1+1)`

`m=(8)/(2)`

`m=4`
