$x\geq2$

On the given graph, there is a closed dot at $2$. This means that $2$ is a solution to the inequality. The number line is shaded to the right of $2$, which says that $x$ is greater than or equal to $2$. Using this information, we know that $x$ is greater than or equal to $2$. We can write this as $x\geq 2$, which is the inequality that represents the graph.
