<PRE><B>Question 1070634</B>
If point A(6,1),B (8,2),C (8,4),D (p,3) are vertices of a parallelogram taken in order, find value of p
------------------
Plot the 3 given points so you can see where the 4th
point would have to be.
------
AC is parallel to BD
AC has a slope of (4-1)/(8-6) = 3/2
----
So BD must have a slope of 3/2
slope of BD :: (3-2)/(p-8) = 3/2
1/(p-8) = 3/2
3p-24 = 2
3p = 26
p = 8 2/3
------------------------
