Which equation is defined as a linear function?

Question

A: y=x^2
B: y=mx+b
C: y=x^3
D: y=/x/

Answer 1

The equation that is defined as a linear function is:

B: y = mx + b

In this equation, \(m\) represents the slope and \(b\) represents the y-intercept. Linear functions have a graph that forms a straight line. The other options (A, C, and D) represent non-linear functions.
