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.
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.
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.
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 between a point \(P\) and a line \(L\) is the shortest distance between \(P\) and \(L\); it is the minimum length required to move from point \( P \) to a point on \( L \). In fact, this path of minimum length can be shown to be a line segment perpendicular to \( L \).
Write a formula for distance from a point to a line. Then count a distance from point $P_1(1,2,4)$ to line $l$, along which intersects the two planes $x+y-2z=1$ and $x+3y-z=4$. I did a matrix $$ \left[ \begin{array}{ccc|c} 1&1&-2&1\\ 1&3&1&4\\ \end{array} \right] $$
