The slash through the 'greater than or equal' sign means 'not (greater than or equal)' or, simplly, 'less than'.
Therefore, your inequality reduces to: -x - 5 < -1
Add 5 to both sides: -x < 4
Divide both sides by -1: x > -4
(When you multiply or divide both sides of an inequality by a negative number, change the direction of the inequality sign.)
Since the domain is the set of negative integers, the answers include -3, -2, and -1.
Place a filled-in circle on -3, on -2, and on -1.
