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

Step-by-step 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]:                    $\displaystyle m=\frac{40-76}{-22-4}$
2. [Fraction] Subtract:                             $\displaystyle m=\frac{-36}{-26}$
3. [Fraction] Simplify:                              $\displaystyle m=\frac{18}{13}$
