#### Answer

y=12

#### Work Step by Step

Since we know that in a direct variation the ratio of $\frac{y}{x}$ is constant, lets divide the two y-coordinates with their respective x-coordinates and set them equal to each other:
$\frac{4}{3}$=$\frac{y}{9}$ (Cross Multiply)
3y=36 (Divide both sides by 3)
y=12
