Find an equation of the plane that contains these lines:
The Attempt at a Solution
I took the cross product of <1,-1,2> and <-1,1,0> to get <-2,-2,0>.
I used the point (1,1,0) to get the equation of the plane:
But the correct answer is supposed to be x+y=2.
I'd really appreciate it if someone could show me what I'm doing wrong. Thanks!
