Given the values of $x$ and $y$, find an equation of variation in which $y$ varies directly as $x$.
-$y=230$, when $x=90$
A) $y=2.56 x$
B) $y=0.39 x$
C) $x=2.56 y$
D) $x=140 y$

Direct variation between $y$ and $x$ can be represented as $y = kx$, where $k$ is the constant of variation. Given $y=230$ when $x=90$, we find $k$ by dividing $y$ by $x$, which gives $k = \frac{230}{90} = 2.56$. Therefore, the equation of variation is $y = 2.56x$.
