Answer 1

y = x - 1

General Formulas and Concepts:

Algebra I

Slope-Intercept Form: y = mx + b

• m - slope
• b - y-intercept

Explanation:

Step 1: Define

Identify variables

Slope m = 1

y-intercept b = -1

Step 2: Write Equation

1. Substitute in general form: y = 1x + -1
2. Simplify: y = x - 1
