The distance (or perpendicular distance) from a point to a line is the shortest distance from a fixed point to any point on a fixed infinite line in Euclidean geometry. It is the length of the line segment which joins the point to the line and is perpendicular to the line. The formula for calculating it can be derived and expressed in several ways.
There are a few ways to find the distance between a point and a line. But the easiest of all is through the use of a formula. The derivation of the formula is reserved for another lesson. The word “distance” here pertains to the shortest distance between the fixed point and the line.
How do we find the shortest distance from a given point on a line to another line? The shortest distance from any point on a line to another line will be the perpendicular distance from the point to the line; If the angle between the two lines is known or can be found then right-angled trigonometry can be used to find the perpendicular distance
The distance between a point \(P\) and a line \(L\) is the shortest distance between \(P\) and \(L\); it is the minimum length required to move from point \( P \) to a point on \( L \). In fact, this path of minimum length can be shown to be a line segment perpendicular to \( L \).
Find the distance between the line \(l=3x+4y-6=0\) and the point \((0,0)\). The distance formula can be reduced to a simpler form if the point is at the origin as: \[d=\frac { \left| a(0)+b(0)+c \right| }{ \sqrt { a^{ 2 }{ +b }^{ 2 } } } =\frac { \left| c \right| }{ \sqrt { { a }^{ 2 }{ +b }^{ 2 } } } .\]

The shortest distance between point and line is calculated by finding the length of the perpendicular drawn from the point to the line. Consider the line l : $Ax + By + C = 0$ and point $P(x₁, y₁)$.
