Answer:

y = $\frac{3}{4}$ x

Step-by-step explanation:

Given that the quantities vary directly then the equation relating them is

y = kx ← k is the constant of variation

To find k use either of the 2 given points

Using (12, 9), that is x = 12 when y = 9, then

k = $\frac{y}{x}$ = $\frac{9}{12}$ = $\frac{3}{4}$

y = $\frac{3}{4}$ x ← equation of variation
