Question

determine which graphs are linear and nonlinear.

Explanation:

Step1: Recall linear graph definition

A linear graph is a straight - line graph.

Step2: Analyze first graph

The first graph is a straight - line, so it is linear.

Step3: Analyze second graph

The second graph is a straight - line, so it is linear.

Step4: Analyze third graph

The third graph is a curved line, so it is nonlinear.

Answer:

First graph: Linear
Second graph: Linear
Third graph: Nonlinear
