We are given coordinates
(-1,1)
(-4,0)
(3,-2)
(0,3)
Solution: First coordinate (-1,1) is on the dotted line. Therefore, (-1,1) not a solution to the following system of inequalities.
Note: Dotted line is excluded from the solution region.
Second coordinate (-4,0) is outside shaded region. Therefore, (-4,0) is not solution to the following system of inequalities.
Third coordinate (3,-2) is exactly on the solid line. Therefore, (3,-2) is a solution to the following system of inequalities.
Note: Solid line included in the solution region.
Fourth coordinate (0,3) is outside shaded region Therefore, (0,3) is not a solution to the following system of inequalities.
