    firstly, you're best drawing a x-y plane and graphing x ≥ 0 and y ≥ 0 (remember to shade regions)

    to know which side of the line to shade you can test any coordiantes which don't lie on that line

    so for e.g. if the line was y > x + 2 I can test (0, 0) because zero is an easy number to test and it doesn't lie on the line, so I can sub (0, 0) in for y and x to get 0 > 0 + 2 so 0 > 2 and this is false, so I would not share on the side where (0, 0) lies
