Answer

The graph is shown below.

Work Step by Step

The inequality is $x\leq-4$ Step 1:- Replace the inequality symbol with $=$ and graph the linear equation. $x=-4$ Graph a vertical line with $x-$ intercept $-4$. The line is solid because equality is included. Step 2:- Choose the solution set using the inequality. In the given equation there is a less than symbol. Hence, the left part of the line is the solution set.
