Question

Please identify whether the relation below models a proportional relationship

Answer 1

Yes because a propprtion is 2 numbers under each other like 12 is under 8 like a fraction form.

Answer 2

The relationship below does not model a proportional relationship. This is due to the fact that when you divide each domain (another word for input, or x) by its range (another word for output, or y), each result it not similar.

For example:

12 / 8 = 1.5

24 / 24 = 1

36 / 32 = 1.125

and so on.

As you can see, the rate changes throughout the table and does not stay similar. Though, it would be proportional if, for example, each x / y were equal to 1.5
