1. Yes, (0, 0) is a solution because it lies within the shaded region of the graph.
2. d. (-3, -1) is a solution because it lies within the shaded region of the graph.
3. No, (-2, 4) is not a solution because it does not lie within the shaded region of the graph.
4. Graph the line y = 3x - 4 as a dashed line and shade below it. Graph the line y = -2x + 1 as a solid line and shade above it. The solution is the overlapping shaded region.
5. Graph the line 2x + y = -4 as a dashed line and shade above it. Graph the line x - 2y = 4 as a solid line and shade above it. The solution is the overlapping shaded region.
6. Graph the line y = (2/3)x + 2 as a solid line and shade below it. Graph the line y = -x - 3 as a dashed line and shade above it. The solution is the overlapping shaded region.
