Expert Solution
Step 1

The equation representing direct variation is y=kx and the equation representing inverse variation is y=kx.

That is, yx will be a constant for direct variation and xy is a constant for inverse variation. If both yx and xy is not a constant then it is neither direct variation nor an inverse variation.
