Question

Is the equation `y=x-2` a direct variation? If it is, how do you find the constant of variation?

Answer 1

`y = x-2` is not a direct variation.

Explanation:

A direct variation means that `y` is proportional to `x`. In other words, they are equations of the form `y = kx` where `k` is a constant value.

`y = x-2` is not of the form `y=kx`, so it is not a direct variation.
