Graphing y<23x5y < \frac{2}{3}x - 5

To graph the inequality y<23x5y < \frac{2}{3}x - 5, follow the three-step procedure: Step 1 — Graph the boundary line. Replace the << symbol with == to get the boundary line y=23x5y = \frac{2}{3}x - 5. Since the inequality is strict (<$), draw a dashed line. Step 2 — Test a point. Use (0, 0)asatestpoint:as a test point:0 \stackrel{?}{<} \frac{2}{3}(0) - 5simplifiestosimplifies to0 < -5.Thisisfalse,so. This is false, so (0, 0)$$ is not a solution. Step 3 — Shade the correct side. Since the test point is not a solution, shade the half-plane on the opposite side of the boundary line (the region below the dashed line).
