Answer
$y=\frac{1}{6}x$
Work Step by Step
As we know a direct variation is present, we can find the relation between x and y by substituting the values into the direct variation equation:
$y=kx$
$\frac{1}{2}=k(3)$
$k=\frac{1}{2}\div3$
$k=\frac{1}{6}$
Then, substitute the k-value into the original equation to get the direct variation:
$y=\frac{1}{6}x$
Then, graph the equation (see attached image).
