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

Step-by-step explanation:

Step 1: Define

Point (-4, 19)

Point (4, 9)

Step 2: Find slope m

1. Substitute:                    $m=\frac{9+19}{4+4}$
2. Add:                              $m=\frac{28}{8}$
3. Simplify:                        $m=\frac{7}{2}$
