So this is basically the question, and I thought I had it figured out most of the way and hit a bump.
I assumed basically the question was x,y,z multiplied by -5,2,-1 would have to give me zero. So I make that into a matrix and solve x = (5/2)s-(1/5)t
witch would be all fine and dandy, but there are three slots? What am I supposed to put in there?? what a weird question... I was wondering if anyone could give me any insight =) thanks!
