This Linear VS Nonlinear Function Graphs activity for 8th grade is an engaging way for your students to analyze functions to determine if the relationship is linear or not linear.

Students choose any 2 colors, color in the two parts of the key, and continue to use those colors for each of the 12 graphs:

• 6 graphs are linear (ex: proportional, nonproportional, positive or negative slope, etc.)
• 6 graphs are nonlinear (ex: absolute value, exponential, etc.)

Includes an optional second page where students can justify their answers from the first page. Students will select 2 graphs from the first page (one linear and one nonlinear), copy those graphs by plotting the given points, create tables of coordinates, and explain how they classified the graphs.
