Find the variation constaant and an equation of variation where Y varies directly as X and Y = 72 hen X = 8

The variation constant is K = ?

The equation of variation is Y = ?

I think that K = 9 but not sure

I don't have a clue about the rest.

"Y varies directly as X" ----> y = kx

but we are given x=8, y = 72

72 = k(8)

k = 9, so

y = 9x

all done!

Thank you, I thought I was on the right track but wasn't sure.
