Work Step by Step
A key note when finding if a graph is linear or not is if it's a line or dots creating a line, it is linear. So, a. the graph is not a straight line so it is nonlinear. b. the graph is a straight line so it is linear c. the graph makes a U shape and is not a line so it is nonlinear. d. The dots in the graph forms a staright line so it is linear.
