The distance between a set of points to the point (-2,0) is the same as the distance between the set of points to the directrix of (2,y).  That description is the definition for a parabola, and is the specific parabola which you want to find.  Translate the description into an equation using the distance formula.  Simplify that equation. </SPAN>\n" );
