• Order of Operations: BPEMDAS

Algebra I

Slope-Intercept Form: y = mx + b

• m - slope

• b - y-intercept

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

Step-by-step explanation:

Step 1: Define

Point (-1, 4)

y-intercept (0, 2)

Step 2: Find slope m

1. Substitute:                    $m=\frac{2-4}{0+1}$
2. Subtract/Add:               $m=\frac{-2}{1}$
3. Divide:                          $m=-2$

Step 3: Write linear equation

y = -2x + 2
