Question

Does the equation `y = 2/x` represent a direct variation and if so, identify the constant of variation?

Answer 1

It represents an inverse proportion with `k=2`

Explanation:

`y = 2/x` can also be written as `xy = 2`

This means that two values multiply together to give `2`.

As `x` gets smaller, `y` gets larger.

`k = xy` defines inverse proportion.

The constant is `2`
