Question Analysis
This question tests the student's ability to interpret a number line and identify the correct inequality symbol that represents the shaded region.

Key Concept Explanation
Inequalities use symbols such as , , , and to compare two expressions. A number line is a visual representation where each point corresponds to a number, and the shaded region indicates the solution set.

Step-by-step Solution
1. Observe the number line and identify the boundary point (-9 in this case).
2. Determine if the boundary point is included or excluded. A closed circle indicates inclusion, while an open circle indicates exclusion.
3. Identify the direction of the shading. If the shading is to the right, the inequality is greater than or equal to (
