FLASHCARD QUESTION

Front

What is a proportional relationship?

Back

A proportional relationship is one in which two quantities maintain a constant ratio, meaning that as one quantity increases or decreases, the other does so in a consistent manner. This relationship can be represented by a straight line that passes through the origin (0,0).

FLASHCARD QUESTION

Front

What is a non-proportional relationship?

Back

A non-proportional relationship is one in which the ratio between two quantities is not constant. This means that as one quantity changes, the other does not change in a consistent manner, and the graph of this relationship does not pass through the origin.
