This form is equivalent to a dot product:
n \cdot x = c
where n is the normalized vector n = (A, B, ...) / | (A, B, ...) |, x is the
vector form of the point and c = Z / | n |
The vector n is unit length and orthogonal to the line and c is the shortest
distance to the origin.
The distance from point p to the line is just
n \cdot p + c
