1. Vectors:Scalar Equation of a Plane in Space Question

What is the scalar equation of the plane that contains the x-axis and the point (4, -2, 1)?

K, I know I need to find the normal to get the scalar equation but I'm confuse on what the x-axis can give? 2 direction vector? And cross product that to find normal?

$N = \left\langle {1,0,0} \right\rangle \times \left\langle {4,-2,1} \right\rangle$
$N = \left\langle {1,0,0} \right\rangle \times \left\langle {4,-2,1} \right\rangle$
