Question Analysis
This question tests the understanding of the boundary line in a two-variable linear inequality. The student needs to recognize whether the boundary line is solid or dashed based on the inequality sign.

Key Concept Explanation
The key concept here is the nature of the boundary line. If the inequality sign is or , the boundary line is solid, indicating that points on the line are included in the solution set. If the inequality sign is < or >, the boundary line is dashed, indicating that points on the line are not included.
