INB 17 Midpoints with Coordinates

image

After some sharing of how to find the midpoints with graph paper – another student suggested he added the coordinates, then divided by 2. 

Find M, the midpoint of AB.  A(7, 3) and B (13, 5)…

x-coordinates:  7+13=20 / 2 = 10 and y-coordinates:  3 + 5 = 8 / 2 = 4 so the midopint will be M(10, 4)
