Midpoint and length

Find the midpoint and length of the line segment PQ where P=(2,-7) and Q=(5,1). We will also use vectors to find the length of the segment.

Solution Preview

The midpoint formula is given by
M = { ( x2+x1)/2 , (y2+y1)/2 }.

This gives the point, the x,y coordinate, that is halfway between the endpoints of the line segment PQ, where P=(2,-7) and Q=(5,1).
