Homework Statement
Find the equation of the plane through the point (2, 5, 7) that is parallel
to the line r = (3i + 2j - 2k) + t(i + 2j + 7k) and perpendicular to the plane 4x + 5y + 6z = 14
It should be written in scalar equation form
Homework Equations
scalar equation of a plane through a point: a(x - x0) + b(y - y0) + c(z - Z0) = 0
normal of a plane is (a, b, c)
cross product of two parallel vectors = 0 (v x u = 0)
The Attempt at a Solution
what I have so far is __(x-2) + __(y-5) + __(z-7)
but i can't figure out how I am supposed to find the normal of this plane...
