Find the coordinates of the midpoint of the segment whose endpoints are (9,3) and (-1,-9).

average x = (8/2) = 4

average y = (0/2) = 0
so
(4,0)

To find the coordinates of the midpoint of a segment, we can average the x-coordinates and the y-coordinates of the endpoints.

Given the endpoints (9,3) and (-1,-9), the x-coordinate of the midpoint is the average of the x-coordinates of the endpoints:

Midpoint x-coordinate = (9 + (-1)) / 2 = 8 / 2 = 4

Similarly, the y-coordinate of the midpoint is the average of the y-coordinates of the endpoints:

Midpoint y-coordinate = (3 + (-9)) / 2 = -6 / 2 = -3

Therefore, the coordinates of the midpoint of the segment is (4, -3).
