  • Slope Formula: [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Step-by-step explanation:

Step 1: Define

Find points from graph.

Point (0, 30)

Point (20, 60)

Step 2: Find slope m

  1. Substitute:                    [tex]m=\frac{60-30}{20-0}[/tex]
  2. Subtract:                       [tex]m=\frac{30}{20}[/tex]
  3. Simplify:                        [tex]m=\frac{3}{2}[/tex]
  4. Divide:                          [tex]m=1.5[/tex]
