Question

How to find shortest distance from a point to a line?

Answer 1

It can be done by using the axis mentioned. If y axis is mentioned then the new point will have the same coordinate of the coordinate mentioned in the question. And the x coordinate will have 0.

Answer 2

The distance between a point  and a line  is the shortest distance between  and ; it is the minimum length required to move from point  to a point on . In fact, this path of minimum length can be shown to be a line segment perpendicular to .

The distance  can then be defined as the length of the line segment that has  as an endpoint and is perpendicular to .
