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

    Step-by-step explanation:

    Step 1: Define

    Point (-1.25, -18.5)

    Point (0.25, -30)

    Step 2: Find slope m

    1. Substitute:                    [tex]m=\frac{-30+18.5}{0.25+1.25}[/tex]
    2. Add:                              [tex]m=\frac{-11.5}{1.5}[/tex]
    3. Divide:                          [tex]m=\frac{-23}{3}[/tex]
