Find the distance from the poinst (-5, 2, -3) to the az-plane.

To find the distance from a point to the $xz$-plane, we are using the formula for the distance between a point and a plane.

The $xz$-plane is defined by the equation $y=0$.

The formula for the distance $d$ between a point $(x_0,y_0,z_0)$ and a plane with equation $Ax+By+Cz+D=0$ is given by

$d=\frac{|A{x}_0+B{y}_0+C{z}_0+D|}{\sqrt{A^2+B^2+C^2}}$
