Answer
$s\geq 9$
The graph is shown below.
Work Step by Step
The given inequality is
$\Rightarrow 1\leq s-8$
Add $8$ to each side.
$\Rightarrow 1+8\leq s-8+8$
Simplify.
$\Rightarrow 9\leq s$
Hence, the solution is $s\geq 9$.
Use a close circle because $9$ is a solution.
Shade the number line on the right side.
