Graphing y52x4y \geq \frac{5}{2}x - 4

To graph the inequality y52x4y \geq \frac{5}{2}x - 4, follow the three-step procedure: Step 1 — Graph the boundary line. Replace the \geq symbol with == to get the boundary line y=52x4y = \frac{5}{2}x - 4. Since the inequality is non-strict (\geq), draw a solid line. Step 2 — Test a point. Use (0,0)(0, 0) as a test point: 0?52(0)40 \stackrel{?}{\geq} \frac{5}{2}(0) - 4 simplifies to 040 \geq -4. This is true, so (0,0)(0, 0) is a solution. Step 3 — Shade the correct side. Since the test point is a solution, shade the half-plane containing (0,0)(0, 0), which is the region above the solid boundary line.
