The midpoint of MN is point P at (–4, 6). If point M is at (8, –2), what are the coordinates of point N?
tester [92]
The midpoint of a line segment is the average of the endpoint's coordinates, mathematically:

mp=((x1+x2)/2, (y1+y2)/2)

In this case:

(-4,6)=((8+x)/2, (-2+y)/2)

(-8,12)=((8+x),(y-2))

(-16, 14)=(x,y)
