Equality Properties

Algebra I

Standard Form: Ax + By = C

Slope-Intercept Form: y = mx + b

m - slope b - y-intercept

Step-by-step explanation:

Step 1: Define

Standard Form:   x + 4y = 12

Step 2: Rewrite

Find slope-intercept form

Subtract x on both sides:                    4y = 12 - xDivide 4 on both sides:                       y = 3 - x/4Rearrange:                                           y = -x/4 + 3
