I WILL MARK YOU BRAINLIEST!!

Butoxors [25]

Answer:

Yes

Step-by-step explanation:

There is a proportional relationship between x and y it's 5.

Think about it when x is 1 y is 5

When x is 2 y is 10

When x is 5 y is 25

When x is 7 y is 35

To get this for this question all you have to do is multiply x by 5 to get y.

That's how you know it's proportional.

Hope this helps!!!
