Find the equation of variation if the following is true.
-Suppose $y$ varies directly as $x$ and $y = 0.9$ when $x = 0.1$.
A) $y = 9 x$
B) $\mathrm { y } = 1 \mathrm { x }$
C) $y = \frac { 1 } { 9 } x$
D) $\mathrm { y } = 0.8 \mathrm { x }$

Direct variation is represented by the equation $y = kx$, where $k$ is the constant of variation. Given $y = 0.9$ when $x = 0.1$, we find $k$ by dividing $y$ by $x$, resulting in $k = \frac{0.9}{0.1} = 9$. Therefore, the equation of variation is $y = 9x$.
