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

Step-by-step explanation:

Step 1: Define

Point (5, -7)

Point (-7, 1)

Step 2: Find slope m

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

1. Substitute in points [SF]:                    $\displaystyle m=\frac{1+7}{-7-5}$
2. [Fraction] Add/Subtract:                     $\displaystyle m=\frac{8}{-12}$
3. [Fraction] Simplify:                              $\displaystyle m=\frac{-2}{3}$
