• Slope Formula:
  `m=(y_2-y_1)/(x_2-x_1)`

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=(-5+1)/(0+1)`
2. Add:
   `m=(-4)/(1)`
3. Divide:
   `m=-4`
