Question

How do you determine whether `5x-y=0` is an inverse or direct variation?

Answer 1

Direct variation.

Explanation:

`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 `1/5` i.e x varies directly `1/5` of y. [Ans}
