Final answer:
The coordinates of point D are (5, 4).
Step-by-step explanation:
To find the coordinates of point D, we can use the midpoint formula. The midpoint of a line segment with endpoints (x1, y1) and (x2, y2) is given by the coordinates [(x1 + x2)/2, (y1 + y2)/2].
In this case, we are given the coordinates of points A(-2, 3), B(6, 7), and C(4, 1). So the coordinates of point D, which is the midpoint of BC, will be [(6+4)/2, (7+1)/2].
Calculating the coordinates, we get D(5, 4). Therefore, the answer is (C) (5, 4).
