Points M(5,2) and N(5,8) lie on the xy  plane. What is the midpoint of line segment MN?A. (5,0) B. (0,5) C. (0, (136^(1/2))/2) D. (3/2,0) E. (1,5) The midpoint of a segment is exactly halfway between its endpoints and it's location can be found using the Midpoint Theorem, which states: • The xcoordinate of the midpoint is the average of the xcoordinates of the two endpoints. • Likewise, the ycoordinate is the average of the ycoordinates of the endpoints. So, x=(5+5)/2=0 and y=(2+8)/2=5 > coordinates of the midpoint are (0, 5). Answer: B. For more on this topic check Coordinate Geometry chapter of Math Book: mathcoordinategeometry87652.htmlHope it helps.

+1 B I think if u visualize it you can see that the midpoint of a line will be the center of the line however it may be aligned in the xy plane. Thus (x1 + x2)/2 , (y1+ y2)/2 is the midpoint I think in school we learnt this as the midpoint formula
