A linear graph is a straight - line graph.

Step2: Analyze each graph

The first graph is a straight - line segment, so it is linear. The second graph is a wave - like curve, not linear. The third graph is a curved line, not linear. The fourth graph is a straight - line segment, so it is linear.

The first and fourth graphs are linear.
