What is a proportional relationship?

Back

A proportional relationship is one in which two quantities maintain a constant ratio or rate. If one quantity increases, the other increases at a consistent rate.

Front

What is a non-proportional relationship?

Back

A non-proportional relationship is one where the ratio between two quantities is not constant. As one quantity changes, the other does not change at a consistent rate.

How can you identify a proportional relationship in a graph?

Back

A graph represents a proportional relationship if it is a straight line that passes through the origin (0,0).

Front

How can you identify a non-proportional relationship in a graph?

Back

A graph represents a non-proportional relationship if it is a straight line that does not pass through the origin or if it is a curve.

Front

What does it mean if a table shows a proportional relationship?

Back

If a table shows a proportional relationship, the ratios of the corresponding values in the table are constant.

Front

What does it mean if a table shows a non-proportional relationship?

Back

If a table shows a non-proportional relationship, the ratios of the corresponding values in the table are not constant.

What is an example of a proportional relationship in real life?

Back

An example of a proportional relationship is the relationship between distance and time when traveling at a constant speed.

Front

What is an example of a non-proportional relationship in real life?

Back

An example of a non-proportional relationship is the relationship between the number of hours worked and the total pay if there is a fixed salary plus overtime.

What is a linear graph?

Back

A linear graph is a graph that represents a linear equation, showing a straight line relationship between two variables.

Front

What is a nonlinear graph?

Back

A nonlinear graph is a graph that represents a nonlinear equation, showing a curved relationship between two variables.
