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

Explanation:

Step 1: Define

Find points from graph.

Point (-4, 0)

Point (0, -2)

Step 2: Find slope m

Simply plug in the 2 coordinates into the slope formula to find slope m. Rate of change is the same as slope.

1. Substitute [SF]:
   `m=(-2-0)/(0+4)`
2. Subtract/Add:
   `m=(-2)/(4)`
3. Simplify:
   `m=(-1)/(2)`
