Q.Does the line with equation (x, y, z) = (5, -4, 6) + u(1,4,-1) lie in the plane with equation (x, y, z) = (3, 0, 2) + s(1,1,-1) + t(2, -1, 1)? Justify your answer algebraically.
What I tried doing:
I started by getting the parametric equation of (x, y, z) = (5, -4, 6) + u(1,4,-1)
I then subbed in u=0 to get a set of points
I then got the parametric equation for (x, y, z) = (3, 0, 2) + s(1,1,-1) + t(2, -1, 1)
I decided to use the points (5,-4,6) and sub them into
I don't know if I'm doing this correctly. I really don't know what to so I tried that.
