What does a graph showing a constant rate of change look like?

Back

A graph showing a constant rate of change is a straight line. The slope of the line represents the rate of change.

Front

What is the formula for calculating rate of change?

Back

The formula for calculating rate of change is: Rate of Change = (Change in Dependent Variable) / (Change in Independent Variable).

Front

What does a higher rate of change indicate?

Back

A higher rate of change indicates a faster increase or decrease in the dependent variable relative to the independent variable.
