<em>Find points from graph.</em>

Point (0, 0)

Point (2, -3)

<u>Step 2: Find slope </u><em><u>m</u></em>

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

  1. Substitute [SF]:                    m=\frac{-3-0}{2-0}
  2. Subtract:                              m=\frac{-3}{2}
