Points M(5,2) and N(5,8) lie on the xy - plane. What is the midpoint of line segment MN?  Options
A) (5,0)	B) (0,5)	C) (0, (136^(1/2))/2)	D) (3/2,0)	E) (5,5)
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 x-coordinate of the midpoint is the average of the x-coordinates of the two endpoints.   • Likewise, the y-coordinate is the average of the y-coordinates of the endpoints.   So, x=(5+5)/2=

5 --&gt; coordinates of the midpoint are (5, 5).   Answer: (5,5).
