Points M(-15,2) and N(5,-5) lie on the xy - plane. What is the midpoint of line segment MN?  Choose the correct choice from the following
A) (5,0)	B) (0,5)	C) (0, (136^(1/2))/2)	D) (-5,-3/2)	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 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=(-15+5)/2=-5 and y=(2-5)/2=-3/2 --&gt; coordinates of the midpoint are (-5, -3/2).   Answer: (-5,-3/2).
