Here's a practice problem.
Given the lines
x = (1,2,-1) + t(3,1,2)
y = (9,0,1) + s(-1,2,1)
a) determine whether they intersect
b) if they intersect find the equation of the plane determined by the lines
Could somebody check my answer please?
I have decided that they do intersect==> -3x - 5y + 7z + 20 = 0
