Plot the lines first.
Then choose a point in the region not on the line.
If the equation is true, that region should be shaded.
Else, the other region.

Choose (0,0), it's convenient.

True, shade the region containing (0,0).

.
Similarly,

Again choose (0,0), it's convenient.

False, shade the region that doesn't contain (0,0).
