Answer
The related equations are graphed to determine the boundaries. The boundaries have either less than or equal to or greater than or equal to signs (and have solid boundaries) or less than or greater than signs (and have dotted boundaries).

Also, a test point is chosen, and the test point cannot be on a boundary line. If the point is part of the solution set, then we shade that region. If the point isn’t part of the solution set, then we shade the other region.
