• Slope Formula: $m=\frac{y_2-y_1}{x_2-x_1}$

Step-by-step explanation:

Step 1: Define

Point (-9, -3)

Point (7, -7)

Step 2: Find slope m

Simply plug in the 2 coordinates into the slope formula to find slope m

1. Substitute [SF]:                    $m=\frac{-7+3}{7+9}$
2. Add:                                     $m=\frac{-4}{16}$
3. Simplify:                               $m=\frac{-1}{4}$
