#### Answer

Interval Notation: [-5, -1]
Number Line: Closed circles on -5 and -1, the area in between these two values on the number line is shaded

#### Work Step by Step

Because -5<=x<=-1,
-5 and -1 are included in the number line.
Therefore, the solution will include all values that are in between -5 and -1, including those two values.
The interval notation uses closed brackets on -5 and -1 because these values are included in the solution.
