WebApr 24, 2024 · To shade the two-variable inequality y<-2x + 3, first graph the line y=-2x + 3. Use a dashed line because the inequality is <, not ≤. Then test an x-y point on one side of the line. If the result makes sense, shade that side of the line. If not, shade the other. For instance, (3,4) gives 4<9, which checks out. Cite this Article WebUse a dashed line if < or > is used to indicate that the boundary is not part of the solution. Shade the appropriate region. Unless you are graphing a vertical line the sign of the inequality will let you know which half-plane to shade. If the symbol ≥ or > is used, shade above the line. If the symbol ≤ or < is used shade below the line.
