Write an equation that gives the proportional relationship of the graph. a) y = 1 8 x b) y = 8x c) y = 9x d) y = 72x

On the graph it says it's 72 and 9 and another one is 144 and 18. Those are the two that I remember.  So all you have to do is divide 72/9=8. 144/18=8 So the proportional relationship is 8.  So the answer is B) y=8x.
                   Hope this helps! :)

The answer is B (Y=8x) I took the test on USA test prep in 7th grade

The answer is 1 because you have to flip the sign when dividing by negative number and 3

Ithink it is 7. 16
