What is The equation for locus of a point P for which the distance from P to (-4,0) is double the distance from P to X-Axis. Plz explain.
given A(-4,0) and let locus of point P be (x,y) and P is 'y' units distant from X-axis also, given PA=2y PA2=4y2 (x+4)2+y2 = 4y2 (x+4)2 = 3y2 The locus is a pair of staright lines: (x+4-31/2y)(x+4+31/2y)=0 -- regards Ramesh

and P is 'y' units distant from X-axis
also, given PA=2y
PA2=4y2
(x+4)2+y2 = 4y2
(x+4)2 = 3y2
The locus is a pair of staright lines: (x+4-31/2y)(x+4+31/2y)=0
