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

Step-by-step explanation:

Step 1: Define

Point (-1, 7)

Point (-3, 1)

Step 2: Solve for x

1. Substitute [SF]:                    $m=\frac{1-7}{-3+1}$
2. Subtract/Add:                      $m=\frac{-6}{-2}$
3. Divide:                                 $m=3$
