2x+3y-5z=0

3x-y+2z=0

I have found the direction vector using the vector product. The answer in the book says the lines goes through point (2,1,1). I think the 0's are a misprint. How do I find that the line goes though that point?

Is it possible to figure out what the constants should be?

The zeroes. If I put the point (2,1,1) into the plane equations I get -4 for the first constant and 7 for the other.

Yes, thanks.
