Question

coordinate of the midpoint of the line segment joining points (11,5) and ( 5,11) is​

Answer 1

Co-ordinates of midpoint of line joining the points (x1,y1) and (x2,y2)=(x1+x2)/2,(y1+y2)/2

Co-ordinates of midpoint of line joining the points (5,−11) and (4,3)=(5+4)/2,(−11+3)/2

= (9/2,−8/2)

= (9/2,−4)

Hence the co-ordinates of midpoint of line joining the points (5,−11) and (4,3) is (9/2,−4).
