Find parametric equations for the line
$$x − 2y + 3z = 4, 2x + y − z = −2$$

I know that the first thing you do is cross the vectors perpendicular to the planes, but I'm having a little trouble finding the point of intersection - can I just set $x, y,$ or $z$ to $0$ and take it from there?

    You need a point to form the equation of the line.2012-12-08

    That's what I'm having trouble finding. Can I just pick an arbitrary point?2012-12-08

    Of course, you can not.2012-12-08

    Wrong question to ask - I'm sleep deprived right now as finals are around the corner. I guess what I was asking in the question was for these two equations, can I just set x, y, or z to 0, and then solving for the two unknowns? I'm terribly confused.2012-12-08
