Answer
$ y\lt -1$
The graph is shown below.
Work Step by Step
The given inequality is
$\Rightarrow -9y\gt 9$
Divide each side by $-9$. Reverse the inequality symbol.
$\Rightarrow \frac{-9y}{-9}\lt \frac{9}{-9}$
Simplify.
$\Rightarrow y\lt -1$
Hence, the solution is $ y\lt -1$.
Use an open circle because $-1$ is not a solution.
Shade the number line on the left side.
