2.) Using any tool (Desmos or by hand on scratch paper) graph the inequality. Select 3 points. One point should be in the solution set, one is not, and one should be on the boundary line. In the boxes below, prove
mathematically that each point matches the description. All steps need to be shown to earn full credit. (6 points)
