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.
The distance from the point to the line is the height of this paralellogram when we consider $\vec{v}=(1,1,1)$ as basis. So the distance is the area divide by the basis. We get the area using the cross product.
Find the perpendicular distance from the point (5, 6) to the line −2x + 3y + 4 = 0. x-intercept p1 = [0, -4/3] y-intercept p2 = [2, 0] shortest distance from p3 = [5, 6] = 3.328
Shows how to find the perpendicular distance from a point to a line, and a proof of the formula.
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.
Learn how to find the perpendicular distance of a point from a line easily with a formula. For the formula to work, the line must be written in the general form.
How to calculate the distance between a point and a line using the formula. Example #1. Find the distance between a point and a line using the point (5,1) and the line y = 3x + 2. Rewrite y = 3x + 2 as ax + by + c = 0. Using y = 3x + 2, subtract y from both sides. y - y = 3x - y + 2. 0 = 3x - y + 2.
