Given the values of $x$ and $y$, find an equation of variation in which $y$ varies directly as $x$.
-$y=0.8$, when $x=0.5$
A) $x=0.8 y$
B) $y=1.6 x$
C) $y=0.8 x$
D) $x=1.6 y$

Direct variation between $y$ and $x$ can be represented as $y = kx$, where $k$ is the constant of variation. Given $y=0.8$ when $x=0.5$, we find $k$ by solving $0.8 = k(0.5)$, which gives $k = 1.6$. Thus, the equation of variation is $y = 1.6x$.
