The midpoint of segment_UV is (5, –11).
The coordinates of one endpoint are U(3, 5).
Find the coordinates of endpoint V.
:
Let the other end point be x2, y2
:
Find x2
%283%2Bx2%29%2F2 = 5
Multiply both sides by 2
3 + x2 = 10
x2 = 10 - 3
x2 = 7
:
Find y2
%285%2By2%29%2F2 = -11
multiply both sides by 2
5 + y2 = -22
y2 = -22 - 5
y2 = -27
:
V endpoint: 7, -27
