A line from P(1,4) to Q(4,-1) is extended to a point R so that PR = 4PQ. Find the coordinate of R.
----------
PQ DATA:
x coordinate change:: 4-1 = 3
y coordinate change:: -1-4 = -5
-------------------------------------
PR DATA:
x coordinate change:: 4*3 = 12
y coordinate change:: 4*-5 = -20
------
Coordinates of R::
x coordinate:: 4 + 12 = 16
y coordinate:: -5+-20 = -25
-----
Ans:: (16,-25)
