Question 455941
Find the other endpoint of a line segment with the given midpoint and one endpoint.
midpoint (11/2,17/2) and the endpoint is (2,9)
..
Midpoint formula: (x1-x2)/2,(y1+y2)/2
For given problem:
(2+x)/2=11/2
2+x=11
x=11-2
x=9
..
(9+y)/2=17/2
9+y=17
y=17-9
y=8
..
ans:
Other endpoint:(9,8)
