Question

is the function y = 7x - 4 linear or nonlinear? linear nonlinear submit

Explanation:

Step1: Recall linear function form

A linear function has the form \( y = mx + b \), where \( m \) (slope) and \( b \) (y - intercept) are constants, and the exponent of \( x \) is 1.

Step2: Analyze given function

For the function \( y = 7x - 4 \), we can see that it is in the form \( y = mx + b \) with \( m = 7 \) (a constant) and \( b=-4 \) (a constant), and the exponent of \( x \) is 1. So it satisfies the definition of a linear function.

Answer:

A. linear
