Answer:

y = 36x

Step-by-step explanation:

Given that x and y vary directly then the equation relating the is

y = kx ← k is the constant of variation

To find k use the condition x = $\frac{1}{3}$ , y = 12, then

k = $\frac{y}{x}$ = $\frac{12}{\frac{1}{3} }$ = 12 × 3 = 36

y = 36x ← equation of variation
