Problem 450. What is the distance from point P(x,y) to the line Ax + By + C = 0?
Given a point, P(x,y), find the distance from this point to a linear line.
INPUTS: x, y, A, B, C
OUTPUTS: d, the distance which of course should always be positive.
EX: >>x=2; y=2; A=2; B=2; C=-4; >>d = normalLen(x,y,A,B,C) d = 1.4142
