Shows how to find the perpendicular distance from a point to a line, and a proof of the formula.
Distance from a point to a line is equal to length of the perpendicular distance from the point to the line. If M 0 (x 0, y 0, z 0) is point coordinates, s = {m; n; p} is directing vector of line l, M 1 (x 1, y 1, z 1) is coordinates of point on line l, then distance between point M 0 (x 0, y 0, z 0) and line l, can be found using the following ...
21 lip 2016 · To find the perpendicular of a given line which also passes through a particular point (x, y), solve the equation y = (-1/m)x + b, substituting in the known values of m, x, and y to solve for b. The slope of the line, m, through (x 1 , y 1 ) and (x 2 , y 2 ) is m = (y 2 – y 1 )/(x 2 – x 1 )
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

Use the slider to change the slope of the red line. The blue line is always perpendicular. Look at the value of m times –1/m. What do you notice?
In this explainer, we will learn how to find the perpendicular distance between a point and a straight line or between two parallel lines on the coordinate plane using the formula. By using the Pythagorean theorem, we can find a formula for the distance between any two points in the plane.
