    please help with my vector homework

    Which of the lines x1 and x2 is perpendicular to the plane with general equation 2x - 2y + 2z = 3?

    x1 = (0, -1, 4) + t(1, -1, 1)

    x2 = (5, 1, 0) + t(2, 0, 1)


    Answer is x1 ...

    I tried dot product of (1, -1, 1) dot (2, -2, 2) to try get 0 (which would mean they are perpendicular) ... but it gives 6....

                The cross product of those two gives you zero, that's your solution I believe.

                    ahhhh, good ol' Calc 3. I did this stuff back in 2008 (spring), I actually found my notebook full of these notes in my closet just now haha with my HWs. I did find something similar to that but I'm pretty much scratching my head since I haven't done this stuff in 2 years
