By rewriting a bit,

$4 \left(x - 0\right) - 2 \left(y - 0\right) + 1 \left(z + 1\right) = 0$,

which is a plane passing through the point $\left(0 , 0 , - 1\right)$ with the normal vector $\vec{n} = \left(4 , - 2 , 1\right)$.

I hope that this was helpful.

This is a visual representation of the plane in a Cartesian system of coordinates
