Question

is the function $y = 7x$ linear or nonlinear?
linear nonlinear

Explanation:

Step1: Recall linear function form

A linear function has the form \( y = mx + b \), where \( m \) is the slope and \( b \) is the y - intercept.

Step2: Compare with given function

The given function is \( y = 7x \). We can rewrite it as \( y=7x + 0 \), which fits the linear function form \( y = mx + b \) with \( m = 7 \) and \( b = 0 \).

Answer:

linear
