This is the direct variation equation $y = k x$ $y=kx$ where $k = \frac{5}{2}$ $k=5/2$ .

We can rearrange the given equation:

$5 x - 2 y = 0$ $5x-2y=0$

Adding $2 y$ $2y$ to both sides:

$5 x = 2 y$ $5x=2y$

$2 y = 5 x$ $2y=5x$

Dividing both sides by $2$ $2$ :

$y = \frac{5}{2} x$ $y=5/2x$

This is the direct variation equation $y = k x$ $y=kx$ where $k = \frac{5}{2}$ $k=5/2$ .
