Question

Use the given endpoint R and midpoint M of RS¯ to find the coordinates of the other endpoint S.

R(3, 0), M(0, 5)

Answer 1

There are 2 answers one two three and four I did this already

Answer 2

Explanation:

the midpoint coordinates between 2 points A and B are

((xa + xb)/2, (ya + yb)/2)

xa = 3

ya = 0

and so we get

(3 + xb)/2 = 0

3 + xb = 0

xb = -3

(0 + yb)/2 = 5

yb = 10

therefore, S = (-3, 10)
