Identify Linear and Nonlinear Functions From Graphs

Practice differentiating between linear and nonlinear functions based on graphs in this eighth-grade algebra worksheet! This one-page practice worksheet asks students to review nine different graphs to determine if the functions shown are linear or nonlinear. Learners will interpret the graphs and apply their knowledge of rate of change and functions to categorize each graph as either linear or nonlinear. As a reminder, linear functions have a constant rate of change, and nonlinear functions do not have a constant rate of change. For detailed examples of linear and nonlinear functions and more practice, check out the Linear vs. Nonlinear: Graphs and Equations worksheet!
