In stereographic projection map, o is the "North pole" (0, 0, -1). Find a parametric equation for the line between o and v = (x, y, z).

$\vec{ov}$ = (x, y, z)-(0, 0, -1) = $< x , y ,z + 1 >$ $r(t)= <0, 0, -1> + t< x , y ,z + 1 >$ $r(t) = < tx,ty,-z-1>$

Is the answer above correct?

Then how do I convert this into an explicit formula? or what does an explicit formula mean?

I removed the graph theory tag since this question doesn't seem to pertain to graph theory (at least not in any obvious way). – benguin Apr 20 '17 at 06:28
Have a look at this answer to a similar question. – Paul Aljabar Apr 20 '17 at 06:44
