X 1 12 x 2 - x 1 x 1 12 x 2 - 12 x 1. In this case we have xy and the value of the midpoint. An alternate solution would be to substitute 44 for x 1 y 1 and 2-5 for xy into the midpoint formula.
X 1 12 x 2 - x 1 x 1 12 x 2 - 12 x 1.
We need to findx and y V is at 29 and the midpoint is at 67. The The midpoint through M parallel to the y-axis bisects the segment A 1A2 at point M. Y y 1 y 2 2. Repeated application of the midpoint formula yields the following.
