Question

Write distance between a point and a line formula.

Answer 1

I THINK IT IS THE ANSWER

Answer 2

Distance between a point and a line is the length of the line segment which joins the point to the line perpendicularly.  

The distance from point (m, n) to the line Ax+By+C=0 is given by

$D=\frac{\mid Am+Bn+C\mid}{\sqrt{A^2+B^2}}$

Where A, B and C are constants

m and n are co-ordinates

So, it is the shortest distance between the length of a perpendicular line segment from the line to the point.
