COORDINATE GEOMETRY 1

Find the midpoint of a line from (13, 4) to (5, 10).

Solution

x1=13, x2=5, y1=4,y2=10.

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

                            2             2

Mid point = (13 + 5,  4 + 10)

                          2          2

Mid point = (18, 14)

                      2    2

Hence midpoint = (9, 7)
