Find the coordinates of the other endpoint of a segment with the given endpoint E and midpoint M. E (14,1) and M (2,13)

Question

I cannot figure this out! Please help!

Answer 1

2 = (X+14)/2

 

4 = x+14

 

x = -10

 

LIkewise

 

13 = (y+1)/2

 

y = 25

 

So the midpoint of (-10,25) and (14,1) is (2,13)
