Find an equation of variation in which y varies inversely as x and the following is true.
-$y = 5$, when $x = 19$
A) $\mathrm { y } = \frac { 0.26 } { \mathrm { x } }$
B) $y = 95 x$
C) $y = \frac { 95 } { x }$
D) $y = \frac { 24 } { x }$

In an inverse variation, $y = \frac{k}{x}$, where $k$ is the constant of variation. Given $y = 5$ when $x = 19$, we find $k$ by multiplying $y$ and $x$, giving $k = 5 \times 19 = 95$. Thus, the equation of variation is $y = \frac{95}{x}$.
