alright, first off remember:  (x,y)  these three points have something obvious to begin with, the x value is the same in all three points.  Therefore every point would be at two on the horizontal plane.  Thus, we have a vertical line!  You know of course this means that the y value is irrelevent and the equation you get is x=2.  for anycombination of x and y values you put together they will come up on this line since x will always be two, and y can be any number you want.  Hope this helps.

Why don't you share with us what you have done so far instead of just asking someone to do your homework?\n\nSorry about the snide remark. Here is your well-deserved step-by-step solution:\nhttp://www.rgetso.com/yahoo/afchica101.pdf

I had a similar problem not long ago. How I solved it was by following the directions at [1]. Hope this helps!

Go here to get a free program, unless you already have one, and there are some tutorials on this website.\nhttp://anim8or.com/main/index.html\nGood luck.

Add them together and divide by 5.\n\nWow. I could seriously have you people do my homework for me. Every night. I'll type out the problems and see how you all do. :P JP

Start as Jim Valentinojr stated:\n\n-1   0  -2 |  -6\n 1   4  -3 | -31\n 5   1  -1 | -28\n\nNow, do row and column operations as he stated until the first element of each row is a "1" and everything below is a "0."\n\nYou will have something that will look like:\n\n1  0  0 | 4\n0  1  0 | 2\n0  0  1 | 3\n\nThen, look at the columns the "1's" are in.  In the bottom row, 1 is in the z column, so the solution in this example is z = 3, y = 2, x = 4.

The link shows how to make calculations using an abacus.  Good luck.

I have found the formula and you could probably input it into a spreadsheet to do the calculations.  This would probably be the easiest way to perfom these complex calculations.
