Answer
$m\lt -7$
The graph is shown below.
Work Step by Step
The given inequality is
$\Rightarrow -9m\gt 63$
Divide each side by $-9$. Reverse the inequality symbol.
$\Rightarrow \frac{-9m}{-9}\lt \frac{63}{-9}$
Simplify.
$\Rightarrow m\lt -7$
Hence, the solution is $m\lt -7$.
Use an open circle because $-7$ is not a solution.
Shade the number line on the left side.
