If y varies directly as x, find the direct variation equation for the situation.
-$y = 0.6$ when $x = 1.2$
A) $y = 0.5 x$
B) $y = 2 x$
C) $y = 0.6 x$
D) $y = x - 0.6$

The direct variation equation is of the form $y = kx$, where $k$ is the constant of variation. Given $y = 0.6$ when $x = 1.2$, we find $k$ by dividing $y$ by $x$, which gives $k = 0.6 / 1.2 = 0.5$. Therefore, the equation is $y = 0.5x$.
