Question

M(4, 2) is the midpoint of RS. The coordinate of S are (6, 1). What are the coordinates of R?

Answer 1

Explanation:

Compare coordinates of S and M

difference in x-coordinates = 4-6 = -2

difference in y-coordinates = 2-1 = 1

x-coordinate of R = x-coordinate of M - 2 = 4-2 = 2

y-coordinate of R = y-coordinate of M + 1 = 3

R(2,3)
