• Slope Formula:
  `m=(y_2-y_1)/(x_2-x_1)`

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=(0+11)/(7-16)`
2. Add/Subtract:
   `m=(11)/(-9)`
3. Rewrite:
   `m=(-11)/(9)`
