Graphing 2x3y<62x - 3y < 6

To graph the inequality 2x3y<62x - 3y < 6, follow the three-step procedure: Step 1 — Graph the boundary line. Replace the << symbol with == to get the boundary line 2x3y=62x - 3y = 6. Since the inequality is strict (<$), draw a dashed line. Step 2 — Test a point. Use (0, 0)asatestpoint:as a test point:2(0) - 3(0) < 6simplifiestosimplifies to0 < 6.Thisistrue,so. This is true, so (0, 0)isasolution.Step3Shadethecorrectside.Sincethetestpointisasolution,shadethehalfplanecontainingis a solution. Step 3 — Shade the correct side. Since the test point is a solution, shade the half-plane containing(0, 0)$$, which is the region above the dashed boundary line.
