Answer:

y = 1/2x - 9

General Formulas and Concepts:

Alg 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: 4x - 8y = 72

Step 2: Find slope-intercept form

  1. Subtract 4x on both sides:          -8y = 72 - 4x
  2. Divide both sides by -8:               y = -9 + 1/2x
  3. Rewrite:                                         y = 1/2x - 9
