Question

If x varies directly to y, and x=3 when y=18, what is the constant of variation?

Answer 1

x varies directly to y means
x=ky
(and y varies directily to x means y=kx, so diffent)



x=3 and y=18
x=ky
3=k18
divide both sies by 18
1/6=k


the constant of variation is 1/6

Answer 2

Your answer is going to be : 6 cause 6 x 3 = 18
