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

Step-by-step explanation:

Step 1: Define

Find points from graph.

Point (2, 5)

Point (4, 9)

Step 2: Find slope m

1. Substitute:                    $m=\frac{9-5}{4-2}$
2. Subtract:                       $m=\frac{4}{2}$
3. Divide:                          $m=2$
