Answer:
C
Explanation:
A point is a solution to the system of inequalities if it lies in the shaded region.
(-3, 3) is on the red dotted line, so it is not a solution.
(1,-2) is below the blue dotted line, so it is not a solution.
(1, 4) is in the shaded region between the lines, so it is a solution.
(-2, 6) is above the red dotted line, so it is not a solution.
