Distance of a Point From a Line

The length of the perpendicular drawn from the point to the line is the distance of a point from a line. The shortest difference between a point and a line is the distance between them. To move a point on the line it measures the minimum distance or length required.

To Find the Distance Between two points:

The following steps can be used to calculate the distance between two points using the given coordinates: 

  • A(m1,n1) and B(m2,n2) are the coordinates of the two given points in the coordinate plane.
  • The distance formula for the calculation of the distance between the two points is, d = √(m2 - m1)2 + (n2 - n1)2
  • Finally, the given solution will be expressed in proper units.

Note: If the two points are in a 3D plane, we can use the 3D distance formula, d = √(m2 - m1)2 + (n2 - n1)2 + (o2 - o1)2.
