Nate at p. f a normal at p(x, y) on a curve meets the x-axis at q and n is the foot of the ordinate at e nq =x(1+y?) 1+ x then the equation of curve given that

nate at P. f A normal at P(x, y) on a curve meets the x-axis at Q and N is the foot of the ordinate at e NQ =X(1+y?) 1+ x then the equation of curve given that it passes through the point (3, 1)is (A) x- y = 8 (B) x+2y2 = 11 (C) x- 5y2 = 4 (DY None of these
