Given the values of $x$ and $y$, find an equation of variation in which $y$ varies directly as $x$.
-$y=50$, when $x=10$
A) $y=50 x$
B) $y=\frac{500}{x}$
C) $y=6 x$
D) $y=5 x$

Direct variation is represented by the equation $y = kx$, where $k$ is the constant of variation. Given $y=50$ when $x=10$, we find $k$ by dividing $y$ by $x$, which gives $k = 50 / 10 = 5$. Thus, the equation of variation is $y = 5x$.
