Mr. Hernandez's sponsor gave him $4.50 for every meter that he walks in the race. Is this relationship proportional or nonproportional, why or why not? MGSE8.EE.5

• Proportional because the rate of change is 0.

• Nonproprtional because the graph would cross at the origin.

• Proportional because it would create a graph that crosses at the origin.

• Nonproportional because the rate of change is $4.50.
