How to measure distance along a line from a specific point

How do you find the distance from a given point to a line?

Quote from video: Form of a line which is y minus y1 equals M times X minus x1 now we know what's going through. This point five five and it's gonna be perpendicular to this line.

How do you find a point that is a certain distance from another point?

Learn how to find the distance between two points by using the distance formula, which is an application of the Pythagorean theorem. We can rewrite the Pythagorean theorem as d=√((x_2-x_1)²+(y_2-y_1)²) to find the distance between any two points.

How do you find the shortest distance from a point to a line vector?

The perpendicular distance between a point and a line is the shortest distance between these two objects. In three dimensions, the perpendicular distance, 𝐷 , between a point 𝑃 ( 𝑥 , 𝑦 , 𝑧 )    and a line with direction vector ⃑ 𝑑 is given by 𝐷 = ‖ ‖  𝐴 𝑃 × ⃑ 𝑑 ‖ ‖ ‖ ‖ ⃑ 𝑑 ‖ ‖ , where 𝐴 is any point on the line.
