(7.4A)- Constant Rate of Change

Front

What is a constant rate of change?

Back

A constant rate of change is a consistent amount of change in a quantity over a specific period of time, often represented as a slope in a graph.

Front

How do you calculate the constant rate of change?

Back

To calculate the constant rate of change, divide the change in the dependent variable by the change in the independent variable (slope = rise/run).
