On a number line, there is a closed point at -2 and shading to the right. Which inequality does it represent?

Answer and explanation

Correct answer: x ≥ -2

The governing concept is the interpretation of endpoints and direction on a number line. A closed or filled point means that the endpoint itself is included in the solution set, so the relation must contain equality. Shading to the right of -2 represents numbers greater than -2. Combining both observations gives x ≥ -2. For example, -2, 0, and 5 satisfy this inequality, whereas -3 does not. Option B has the correct direction but uses an open endpoint and therefore excludes -2. Options C and D describe the left side of the number line, so they do not match the diagram. Therefore, option A is unambiguously correct.
