Question Analysis
This question tests the student's understanding of the boundary line and its representation in a linear inequality. The key is to recognize that the boundary line for the inequality is and that it should be solid because the inequality includes the equal sign.

Key Concept Explanation
The boundary line of a linear inequality is the line that divides the coordinate plane into two regions. If the inequality includes an equal sign (≤ or ≥), the boundary line is solid, indicating that points on the line are part of the solution set.
