$b\leq-\frac{1}{6}$
$18b\leq-3\longrightarrow$ divide both sides by 18 $18b\div 18\leq-3\div18\longrightarrow$ divide $b\leq -\frac{1}{6}$ Check the endpoint. $18(-\frac{1}{6})\overset?=-3$ $-3=-3\checkmark$ Check the inequality. $18(-{1})\overset?\leq-3$ $-18\leq-3\checkmark$ Since $-\frac{1}{6}$ is included in the solution, the endpoint of the graph is a solid circle.
