if (2, -5) is the endpoint of a line segment and (4,-1) is its midpoint find the other endpoint

Question

if (2, -5) is the endpoint of a line segment and (4,-1) is its midpoint find the other endpoint

Answer 1

(2,-5)_________(4,-1)________(x,y)

(-5+y)/2=-1 and (2+x)/2=4

-5+y=-2

y=3

2+x=8

x=6

(6,3) is the other endpoint
