Figure 6.5-6 ii?a#39; _l The graph of a linear inequality is a region that is a closed or an open half-plane. To see how such a region is determined, let us sketch the graph of the linear inequality x ay + 3 $0, which we first write in the equivalent form y2x+3.

In actual practice, sketching the graph of a linear inequality usually requires just two steps. Figure 6.5-7 l.
