$5 x - y = 0 or 5 x = y or x = \frac{y}{5} or \frac{x}{y} = \frac{1}{5}$ $5x-y=0 or 5x =y or x = y/5 or x /y = 1/5$ (constant)

This is a direct variation , as y increases , x increases.

In inverse variation , as y increases , x decreases.

The constant of variation is $\frac{1}{5}$ $1/5$ i.e x varies directly $\frac{1}{5}$ $1/5$ of y. [Ans}
