Question

Is `y/x = 8` a direct variation equation and if so what is the constant?

Answer 1

`y/x=8` is a direct variation equation where `8` is the constant.

Explanation:

In a direct variation `ypropx` i.e. `y=kx`, where `k` is a constant.

Hence, `k=y/x` and as here `y/x=8`,

and as such `y/x=8` is a direct variation equation where `k=8` is the constant.
