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

Step-by-step explanation:

Step 1: Define

Point (1, -3)

Point (0, -1)

Step 2: Find slope m

Substitute in points into the slope formula to find rate of change

1. Substitute [SF]:                    $m=\frac{-1+3}{0-1}$
2. Add/Subtract:                      $m=\frac{2}{-1}$
3. Divide:                                 $m=-2$
