3.1 Constant Rate of Change

Front

What is the constant of proportionality?

Back

The constant of proportionality is the ratio between two proportional quantities, indicating how one quantity changes in relation to another.

Front

What is rate of change?

Back

Rate of change describes how one quantity changes in relation to another quantity.

Front

What does a constant rate of change indicate on a graph?

Back

A constant rate of change indicates a straight line on a graph, showing a consistent relationship between the two variables.

Front

What is a proportional relationship?

Back

A proportional relationship is one where two quantities maintain a constant ratio or rate of change.

Front

What is a non-proportional relationship?

Back

A non-proportional relationship is one where the ratio between two quantities is not constant.

Front

How do you find the rate of change from a table?

Back

To find the rate of change from a table, divide the change in the dependent variable by the change in the independent variable.

Front

What does a slope of 0 indicate on a graph?

Back

A slope of 0 indicates that there is no change in the dependent variable as the independent variable changes.

Front

What is the formula for calculating the slope (rate of change)?

Back

The formula for calculating the slope is (change in y) / (change in x).

Front

What does a positive slope indicate?

Back

A positive slope indicates that as one quantity increases, the other quantity also increases.

Front

What does a negative slope indicate?

Back

A negative slope indicates that as one quantity increases, the other quantity decreases.
