Harry and Sandy wish to meet at a point in Hogwarts that is at the midpoint of their coordinates. Harry is standing at (9,-2), and Sandy is standing at (-1,8). At what coordinate will they meet?
Midpoint formula :
( add x coordinates / 2 , add y coordinates / 2 ) .....so.....
[ ( 9 -1) / 2 , ( 8 - 2) / 2 ] =
[ 8 / 2 , 6 / 2 ] =
( 4 , 3 ) = meeting point
