Question

The coordinates of the midpoint of mn are (4. 1). the coordinates of point mare (-2,5).

what are the coordinates of point n?

Answer 1

(10, 3)

Midpoint = ([x1 + x2]/2 , [y1 + y2]/2)

(4, 1) = ([-2 + x]/2, [5 + y]/2)

4 = (-2 + x) / 2
8 = -2 + x
x = 10

1 = (5 + y) / 2
2 = 5 + y
y = -3

Check

(4, 1) = ([-2 + x]/2, [5 + y]/2)

(4, 1) = ([-2 + 10]/2, [5 - 3]/2)

(4, 1) = (8/2 , 2/2)

(4, 1) = (4, 1) :)
