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

Explanation:

Step 1: Define

Point (4, 76)

Point (-22, 40)

Step 2: Find slope m

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

1. Substitute in points [SF]:
   `\displaystyle m=(40-76)/(-22-4)`
2. [Fraction] Subtract:
   `\displaystyle m=(-36)/(-26)`
3. [Fraction] Simplify:
   `\displaystyle m=(18)/(13)`
