What is a Proportional Relationship?

Back

A proportional relationship is a relationship between two quantities where the ratio of one quantity to the other is constant. This means that as one quantity increases, the other quantity increases at a consistent rate.

What is a Non-Proportional Relationship?

Back

A non-proportional relationship is a relationship between two quantities where the ratio is not constant. This means that as one quantity increases, the other quantity does not increase at a consistent rate.

What does it mean if a graph is a straight line that goes through the origin (0, 0)?

Back

If a graph is a straight line that goes through the origin (0, 0), it indicates a proportional relationship between the two variables.

What is the slope of a proportional relationship?

Back

The slope of a proportional relationship is constant and can be calculated as the change in the y-values divided by the change in the x-values.
