Question

Does the equation `-x + 4y = -2` represent a direct variation and if so, identify the constant of variation?

Answer 1

`-x+4y=-2` is not a direct variation.

Explanation:

One of the (but not the only) characteristics of a direct variation equation is that `(x,y)=(0,0)` will always be a valid solution.

`(0,0)` is not a valid solution for `-x+4y=-2`
