Solve it like an EQUALITY first and you get a line, right? Slope of 4 and a y-intercept of -5. The inequality simply means that anythin above that line (or on it) satisfies the equation. Its much easier to see graphically.
Using trial solution will be helpful also. (0,-5);(1,-1),(-2,-13) are all solution on the line.

Let's do some guess and check.
If x = 2, then y needs to be 4 or 5 or...so ordered pairs would be (2,4) (2,5)
If x = 3, then y needs to be 7 or 8 or 9
(3,7) (3,8) (3,9)
Because this is an inequality, the answers exist in a half-plane, so the possibilities are endless, but you only needed one.
