Work Step by Step
The solutions of the given inequality are the numbers that greater than or equal to $-2$ but are less than or equal to $0$.
To graph the solutions on a number line, plot solid dots at $x=-2$ and $x=0$ (alternatively, a bracket may be used instead of a solid dot).
Then, shade the region between the two.
