An easy to use calculator to find the distance d between a line of the general form ax + by + c = 0 and a point given by its coordinates P(x0,y0).
The formula for the distance d is given by
d = |a·x0 + b·y0 + c| / √(a2 + b2)
How to use the calculator
1 - Enter the coefficients a, b and c and the coordinate of the point and press "enter".
