Question

What is the slope- intercept form of 4x+5y=20

Answer 1

y = -4/5x + 4

General Formulas and Concepts:

Pre-Algebra

• Equality Properties

Algebra I

Standard Form: Ax + By = C

Slope-Intercept Form: y = mx + b

• m - slope

• b - y-intercept

Explanation:

Step 1: Define

Standard Form: 4x + 5y = 20

Step 2: Rewrite

1. Subtract 4x on both sides: 5y = 20 - 4x
2. Divide 5 on both sides: y = 4 - 4/5x
3. Rearrange: y = -4/5x + 4
