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

Explanation:

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

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