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

Step-by-step explanation:

Step 1: Define

Find points from table.

Point (-1, -1)

Point (0, -5)

Step 2: Find slope m

Simply plug in the 2 coordinates into the slope formula to find slope m.  Rate of change and slope are identical.

1. Substitute [SF]:                    $m=\frac{-5+1}{0+1}$
2. Add:                                     $m=\frac{-4}{1}$
3. Divide:                                 $m=-4$
