Find the perpendicular distance from a point to a line in general form. The page evaluates the displayed equation from your supplied values and presents both symbolic and substituted KaTeX working so the arithmetic can be checked.
d = |Ax_0+By_0+C|/sqrt(A^2+B^2)

Use boundary
At least one of line coefficients A and B must be nonzero.
Use internally consistent units and retain extra precision when carrying the result into another calculation.
