When graphing a strict inequality boundary, what boundary line style is used?

Explanation:
When graphing a strict inequality, the boundary line is drawn as dashed. This shows the points on the line itself are not included in the solution set, since the inequality is strict (< or >). If the inequality were non-strict (≤ or ≥), the boundary would be a solid line to indicate those boundary points are included in the solution. Shading then appears on the side that satisfies the inequality.
