M is the midpoint of RS and R has coordinates (2, 5). M has coordinates (6, 9).
Find the coordinates of S.
A.
(16, 16)
B.
(4.5, 6.5)
C.
(4, 4)
D.
(10, 13)
To find the coordinates of S, we need to determine the change in x and change in y from R to M, and then apply those changes to the coordinates of M.
Change in x: 6 - 2 = 4
Change in y: 9 - 5 = 4
Therefore, from the coordinates of M (6, 9), we subtract the changes to find the coordinates of S:
x-coordinate of S: 6 - 4 = 2
y-coordinate of S: 9 - 4 = 5
So, the coordinates of S are (2, 5).
Therefore, the correct answer is:
C.
(2, 5)
