How Far is a Point from a Line in Geometry? - legacy
Can a line be infinite in length?
where d is the distance, A, B, and C are coefficients from the line equation, and x and y are the point's coordinates.
d = |(P * (a * b - c * d) + Q * (c * a - b * d) + R * (b * c - a * d)) / sqrt((a^2 + b^2 + c^2))|

Who is this topic relevant for?
In geometry, a point is a location in space, while a line is a set of infinite points extending in two directions. When we talk about the distance between a point and a line, we're essentially asking how close or far the point is from the line. This can be visualized using a coordinate plane, where the line is represented by an equation (e.g., y = x + 1) and the point is a specific coordinate (e.g., (3, 4)). The distance between the point and the line can be calculated using the formula:
