Answer
The second step is wrong, the correct solution is $x\geq 1$.
The correct graph is shown below.
Work Step by Step
The given inequality is
$\Rightarrow -10+x\geq -9$
Add $10$ to each side.
$\Rightarrow -10+x+10\geq -9+10$
Simplify.
$\Rightarrow x\geq 1$
Use a close circle because $1$ is a solution.
Shade the number line on the right side.
Hence, the second step is wrong, the correct solution is $x\geq 1$.
