Stereographic projection is a map-making technique that takes points on a sphere with radius one unit (Earth) to points on a plane (the map). The plane is tangent to the sphere at the origin.

The map location for each point P on the sphere is found by extending the line that connects N and P. The point's projection is where the line intersects the plane. Find the distance d from the point P to its corresponding point P'(4, -3) on the plane.
