Answer: No, it is not a direct variation

==========================================================

Step-by-step explanation:

The given equation solves to y = x-3, which is not in the form y = kx. So the original equation is not a direct variation.

An example of a direct variation would be y = 5x, where in this case, k = 5.

Visually, all direct variation equation graphs go through the origin.
