Question

K is the midpoint of JL , The coordinates of K are (-2,3) and the coordinates of L (2,-1). What are the
coordinates of endpoint J?
F (6, −5)
G (−6, 7)
H (0, 1)
J (−4, 5)

Answer 1

First use distance formula to find distance between K and L.

Answer 2

If A=(x, y) and B=(p, q), then the midpoint of line segment AB is just
([x+p]/2 , [y+q]/2)
