After graphing the lines, you can see that the solution is (4, -1)
Answer:
Step-by-step explanation:
Answer:
y = 1/2x - 9
General Formulas and Concepts:
<u>Alg I</u>
Standard Form: Ax + By = C
Slope-Intercept Form: y = mx + b
Step-by-step explanation:
<u>Step 1: Define</u>
Standard Form: 4x - 8y = 72
<u>Step 2: Find slope-intercept form</u>
- Subtract 4x on both sides: -8y = 72 - 4x
- Divide both sides by -8: y = -9 + 1/2x
- Rewrite: y = 1/2x - 9
