To determine the slope, you can use the following formula:

(y2-y1)/(x2-x1)
MathGenius04
The distance formula is one method

The change in y over the change in x equals the slope.

(-7, 3) & (1, -9)

To get from 1 to -7 you subtract 8
To get from -9 to 3 you add 12

12/-8 reduces to 3/-2

The slope is 3/-2
