COORDINATE GEOMETRY 1

Find the midpoint of a line from (13, 12) to (5, 10)

Solution

x1=13, x2=5, y1=12,y2=10.

Mid point = (x1 + x2, y1 + y2)

                          2             2

Mid point = (13 + 5,  12 + 10)

                         2          2

Mid point = (18, 22)

                      2     2

Hence midpoint = (9, 11)
