Answer:
Step-by-step explanation:
Refer to the attached figure. Note that the solution set is shaded, and includes all points on the solid boundary line.
black point (-1,1) is outside of the solution set
Red point (1,-1) is also outside of the solution set.
Yellow point (3,2) is on the solid boundary line, so it is part of the solution set
Blue point (2,3) is outside of the solution set.
