Answer:
Graph the dashed line (>) 2x - 3y = 18. This will have a y-intercept of (0, -6) and an x-intercept of (9, 0). Test a point on each side of the line. Testing the point (10, 0), which is below the line: 2(10) - 3(0) > 18, 20 > 18. Since this is a true statement, the shading is on that side (below) the line.
