Answer
$ w\geq -80$
The graph is shown below.
Work Step by Step
The given inequality is
$\Rightarrow \frac{w}{-5}\leq 16$
Multiply each side by $-5$. Reverse the inequality symbol.
$\Rightarrow -5\cdot (\frac{w}{-5})\geq -5\cdot 60$
Simplify.
$\Rightarrow w\geq -80$
Hence, the solution is $ w\geq -80$.
Use a close circle because $-80$ is a solution.
Shade the number line on the right side.
