Graphing Rotation of ellipse



Can anyone tell me how to graph the following ellipse:

   7X^2 - 6sqrt(3)XY + 9Y^2 - 16 = 0

I have a TI-82 and a TI-83 for classroom demos and a personal TI-85, but
would prefer not to use it.  If there is no way on the TI's, is there a
graphical program for the computer?
