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

I can help you solve problems involving fractions, decimals, ratios, and algebra. I can teach you how to do math faster, and even in your head. I can teach math definitions, and help you study, if necessary. Please do not ask any graphing, trigonometry, or calculus questions. Try to work through homework questions before asking for assistance.

I routinely process numbers of all kinds in my head, without need of a calculator.**Education/Credentials**

I was an A math student while in high school.
