Question

M(5.9) is the midpoint ofRS. The coordinates of Sare (6,8). What are the coordinates of R?

Answer 1

Coordinates of R (4,10)

•————•————•
(?,?) (5,9) (6,8)

You have to see how the x & y changed from point M to S and do the same thing for point R to M


M S
(5,9) >>>> (6,8) (x+1, y-1)

R M
(4, 10) >>>> (5,9) (x+1, y-1)
