Question

What is the slope intercept form of the equation 4x-8y=72

Answer 1

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

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
