From any point on the line 2x + y = 1, tangents are drawn to the circle x^2 +y^2 = 9, then the chords of contact pass through a fixed point (A) (18, 9) (B) (9, 18) (C) (9,9) (D) (18,18)

Assume that point in parametric form on line 2x + y = 1 as: (x , 1-2x) and apply chords of contact concept here that is: T = 0. and put the point (x,1-2x). and try to satisfy the options...
