1. Graph the line . Use a dashed line because the original inequality is strictly less than.
2. Select any point on the plane that is NOT on the boundary line you just drew. Any time the line does not go through the origin (i.e. ), as in this case, the origin is an outstanding choice for this step.
3. Replace the variables in the original inequality with the coefficients of the point you selected in step 2.
4. If the result of step 3 is a true statement, shade in the half-plane on the side of the boundary line that CONTAINS the point selected in step 2. Otherwise, shade in the opposite side of the boundary line.
