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

Step-by-step explanation:

Step 1: Define

Point (16, -11)

Point (7, 0)

Step 2: Find slope m

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

1. Substitute [SF]:                    $m=\frac{0+11}{7-16}$
2. Add/Subtract:                      $m=\frac{11}{-9}$
3. Rewrite:                               $m=\frac{-11}{9}$
