Question

Is the equation a linear function or nonlinear function?
y = 0.5x – 1

Answer 1

Linear.

General Formulas and Concepts:

Algebra I

Slope-Intercept Form: y = mx + b

• m - slope

• b - y-intercept

Explanation:

Step 1: Define

y = 0.5x - 1

Step 2: Compare

y = mx + b

y = 0.5x - 1

m = 0.5

b = -1

The equation is a linear function. It's proportional.
