Question Analysis
This question tests the student's ability to recognize and write an inequality based on a given boundary line in a graph. The shaded region indicates that all points on or to the left of the line are part of the solution set.

Key Concept Explanation
In a system of inequalities, the boundary lines are determined by the corresponding equations. The type of line (solid or dashed) and the shading indicate whether the boundary is included in the solution set.

Step-by-step Solution
1. Identify the vertical line at on the graph.
2. Observe that the shaded region includes all points on or to the left of this line.
3. Since the line is solid, the boundary is included in the ...
