Point-Line Distance

The distance from a point, P, to a line, r, is the smallest distance from the point to one of the infinite points on the line.

This distance corresponds to the perpendicular line from the point to the line.

1. Determine the distance from the point P = (1, 3, −2) to the line.

2. Determine the distance from the point P = (1, 2, 3) to the line.
