Given the values of $x$ and $y$, find an equation of variation in which $y$ varies directly as $x$.
-$y=36$, when $x=16$
A) $y=2.25 x$
B) $y=0.44 x$
C) $y=2.25 y$
D) $y=36 x$

Direct variation between $y$ and $x$ can be expressed as $y = kx$, where $k$ is the constant of variation. Given $y=36$ when $x=16$, we find $k$ by dividing $y$ by $x$, which gives $k = 36 / 16 = 2.25$. Therefore, the equation of variation is $y = 2.25x$.
