hartnn · Answer

since y varies DIRECTLY with 'x'
we have 
$\Large y=kx$
where k is the constant of proportionality.

miracrown · Answer

When something varies directly is telling us that the more of y you will get more of x.

hartnn · Answer

can you find the value of k ?

3 = k * 15
k = ... ?
