Answer
$ g\geq -20$
The graph is shown below.
Work Step by Step
The given inequality is
$\Rightarrow -4\leq \frac{g}{5}$
Multiply each side by $5$.
$\Rightarrow 5(-4) \leq 5(\frac{g}{5})$
Simplify.
$\Rightarrow -20\leq g$
Hence, the solution is $ g\geq -20$.
Use a close circle because $-20$ is a solution.
Shade the number line on the right side.
