Exploring Rate of Change in Other Situations 4

In this rate of change in other situations instructional activity, 9th graders solve 12 different types of problems related to determining the rate of change in various situations. First, they complete the table at the top to show how the defect rate remains constant and then, find the rate of change. Students also determine the constant rate of proportionality in the situation and which equation models that y is proportional to x.
