The distance between a point and a line, is defined as the shortest distance between a fixed point and any point on the line. It is the length of the line segment that is perpendicular to the line and passes through the point.
Drop a perpendicular from the point P with coordinates ( x0, y0) to the line with equation Ax + By + C = 0. Label the foot of the perpendicular R. Draw the vertical line through P and label its intersection with the given line S.
Shows how to find the perpendicular distance from a point to a line, and a proof of the formula.
This online calculator uses the line-point distance formula to determine the distance between a point and a line in the 2D plane. Distance between a line and a point supports lines in both standard and slope-intercept form
Learn how to calculate the perpendicular distance between a line and a random point in Excel, determine the side on which the point is located, and check if the point is within the line segment.
To compute the length of a 2D line given the coordinates of two points on the line, you can use the distance formula, adapted for Excel's formula syntax. In the example shown, the formula in G5, copied down, is: =SQRT((D5-B5)^2+(E5-C5)^2) where the coordinates of the two points are given in columns B through E.
