Homework Statement
Find an equation for the plane that is perpendicular to the line x = 3t -5, y = 7 - 2t, z = 8 - t, and that passes through the point (1, -1, 2).
Homework Equations
Equation of a plane: Ax + By + Cz = D
D = Axo + By0 + Cz0
The Attempt at a Solution
I am not sure how to get the line x, y and z into the vector form <A,B,C>
thinking...
1 = 3t - 5...t = 2
-1 = 7 - 2t...t = 4
2 = 8 - t...t = 6
But using that in the equation of a plane does not seem to work. A little confused :(
Answer is : 3x - 2y - z = 3
