#### Answer

y=-6

#### 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:
$\frac{y}{1}$=$\frac{-9}{\frac{3}{2}}$. (Cross Multiply)
$\frac{3y}{2}$=-9 (Multiply both sides by 2)
3y=-18 (Divide both sides by 3)
y=-6
