$-7\frac{1}{2}\leq n$
$6\geq-\frac{4}{5}n\longrightarrow$ multiply each side by $-\frac{5}{4}$; reverse the inequality sign $6\times-\frac{5}{4}\leq-\frac{4}{5}n\times-\frac{5}{4}\longrightarrow$ multiply $-7\frac{1}{2}\leq n$ The endpoint of the graph is a solid circle since$-7\frac{1}{2}$ is in the solution set.
