Answer
$x\leq8$
Work Step by Step
On the given graph, there is a closed dot at $8$. This means that $8$ is a solution to the inequality. The number line is shaded to the left of $8$, which says that $x$ is less than or equal to $8$.
Using this information, we know that $x$ is less than or equal to $8$. We can write this as $x\leq 8$, which is the inequality that represents the graph.
