The endpoints of a line segment are (2, 3) and (8, 15). What is the sum of the coordinates of the midpoint of the segment?
Midpoint : Add the x values and divide by 2.....Add the y values and divide by 2....so we have
[ ( 8 + 2) / 2 , ( 15 + 3) / 2 ] =
[ 10 / 2 , 18 / 2 ]
( 5 , 9 )
Sum of midpoint coordinates = 14
