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.
