Midpoints: The midpoint of the segment that connects (xy and xy can be found by averaging the x-coordinates and averaging the y-coordinates.
x + xy + M = 2 2
The midpoint of the segment connecting 4, -1 and (0, 2) is
M = 12
Find the midpoint of the segment with the given end points: (1, 2), (3, 5) and (8, 0), and (0, 8)
(2, -3), (1, -1) and (8, 5)
(0, -2) and (4, -4)
(-5, -3) and (-1, -1)
