Question

HELP PLEASE! IS THIS PROPORTIONAL??

Answer 1

Porportional

Explanation:

-1 x = -15 y

-7 x -15 = -105, correct

-9 x -15 = -135, correct

Because all are correct, this is porportional. This means that there is a unit rate and if this were graphed, the line would be straight.

I Hope That This Helps! :)
