If y varies directly as x, find the direct variation equation for the situation.
-$y = 12 \text { when } x = 16$
A) $y = x - 4$
B) $y = \frac { 4 } { 3 } x$
C) $y = \frac { 3 } { 4 } x$
D) $y = 4 x$

In direct variation, $y = kx$. Given $y = 12$ when $x = 16$, solve for $k$: $12 = k \times 16$, so $k = \frac{3}{4}$. Thus, the equation is $y = \frac{3}{4}x$.
