Question
What is proportional relationship?

Hello, Stephanie.

A proportional relationship is one in which, for example, as X increases by 5, Z will also increase by 5. The two are therefore proportional one to another.

x+2 = y is a proportional relationship between x and y. If x is 1, then y = (1+2), or 3. If x increases by 1, then y increases by 1 (2+2=4). If x increases by 10, then y increases by 10, and so on.

Hope this helps.

Regards,
John
