If the number line has a closed circle at -5 and shading to the right, what is the inequality?

Answer and explanation

Correct answer: x ≥ -5

The governing concept is combining endpoint inclusion with the direction of shading. A closed circle at -5 means that -5 belongs to the solution set, so the inequality must include equality. Shading to the right represents numbers greater than -5 because values increase from left to right on the number line. Therefore the inequality is x ≥ -5, making option D correct. Option C has the correct rightward direction but excludes -5 and would need an open circle. Options A and B point left, representing values less than -5; B includes the endpoint but has the wrong direction. In interval notation, the graph is [-5, ∞), which also confirms inclusion of -5 and extension toward larger values.
