(B) Angle made by line √3x + y = 1 with positive x-axis in anti-clockwise direction is 120°. Now the required line makes either 180° or 60° angle with + x-axis. But required line is not parallel to x-axis. So slope of required line is tan 60° = √3 ⇒ required line is (y + 2) = √3 (x – 3) ⇒ y – √3x + 2 + 3 = 0
