Answer :

Given that we need to find the point on parabola x2 = 9y such that the abscissa is three times the ordinate.



Let us assume the point be (3y1, y1). Substituting in the parabola we get,


(3y1)2 = 9(y1)


9y12 = 9y1


y12 - y1 = 0


y1(y1 - 1) = 0


y1 = 0 or y1 - 1 = 0


y1 = 0 or y1 = 1


The points is B(3(1), 1) i.e, (3, 1).


The point is (3, 1).
