Final answer:
The coordinates of point D are (-3, 8).
Step-by-step explanation:
The coordinates of point D can be found by using the formula (xD, yD) = (xA + xB + xC, yA + yB + yC), where (xA, yA) = (0, 4), (xB, yB) = (0, 2), and (xC, yC) = (-3, 2).
Substituting these values into the formula, we get (xD, yD) = (0 + 0 + (-3), 4 + 2 + 2) = (-3, 8).
