Answer
$m\le8$
Refer to the graph below.
Work Step by Step
Add $3$ to each side:
$\begin{align*}
m-3+3&\le5+3\\
m&\le8
\end{align*}$
Use $0$ as a test number:
$\begin{align*}
m&\le8\\
0&\le8
\end{align*}$
The statement above is true so shade the region where $0$ is located.
Use an open circle to obtain the graph below.
