Question

Is `x = 3/y` an inverse or direct variation?

Answer 1

Inverse

Explanation:

Directly proportional means that `y=kx` for `k` constant, while inversely proportional means that `y=k/x` for `k` constant.

Given: `x=3/y`.

`:.xy=3`

`y=3/x`.

Comparing now `y=k/x` and `y=3/x`, we see easily that `k=3`, and this is an inverse variation.
