Concept:A filled dot on a number line means the endpoint is included, and the arrow direction shows the set of numbers that satisfy the inequality.Explanation:The number line has a filled dot at $2$, so $2$ is included in the solution.The arrow extends to the right, meaning all numbers greater than $2$ are included.Since $2$ is included and the values increase to the right, the inequality is $x \geq 2$.Answer:$x \geq 2$Option C.
