<PRE><B>Question 515141</B>
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
{{{(3+x2)/2}}} = 5
Multiply both sides by 2
3 + x2 = 10
x2 = 10 - 3
x2 = 7
:
Find y2
{{{(5+y2)/2}}} = -11
multiply both sides by 2
5 + y2 = -22
y2 = -22 - 5
y2 = -27
:
V endpoint: 7, -27</PRE>
