If for each x the associated y = kx, and k is always the same regardless of which (x,y) pair that you examine, then this is direct variation.

Now let's consider:

x: 1 2 3 4

y: 1 ½ 1/3 0.25

If for each x the associated y = k/x & k is always the same for each (x,y) pair, then it's inverse variation.
