General Formulas and Concepts:

Pre-Algebra

• Order of Operations: BPEMDAS

Algebra I

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

Step-by-step explanation:

Step 1: Define

Point (-4, 7)

Point (2, -8)

Step 2: Find slope m

1. Substitute:                    $m=\frac{-8-7}{2+4}$
2. Subtract/Add:               $m=\frac{-15}{6}$
3. Simplify:                        $m=\frac{-5}{2}$
