The variables x and y vary directly. Use the values to find the constant of proportionality, k. Then write an equation that relates x and y.

Y/X=? Basically saying that 72 divided by 3 is what
y = kx
Replace y and x to solve for k:
72 = 3k
Divide both sides by 3:
k = 24
Now replace k with 24:
y = 24x
