Final answer:
The midpoint of the line segment CD is (2, 2).
Step-by-step explanation:
To calculate the midpoint of the line segment CD, we need to find the average of the x-coordinates and the average of the y-coordinates of points C and D.
The x-coordinate of the midpoint is found by taking the average of -4 and 8, which is (-4 + 8) / 2 = 4 / 2 = 2.
The y-coordinate of the midpoint is found by taking the average of 8 and -4, which is (8 + (-4)) / 2 = 4 / 2 = 2.
Therefore, the midpoint of the line segment CD is (2, 2).
