JEE Main 30 June 2022, Shift 1, Maths Q13

Question 13 of 90 in this shift, Maths question 13 of 30, Section A.

Let α1,α2\alpha_1, \alpha_2 (α1<α2\alpha_1 < \alpha_2) be the values of α\alpha for the points (α,−3)(\alpha, -3), (2,0)(2, 0) and (1,α)(1, \alpha) to be collinear. Then the equation of the line, passing through (α1,α2)(\alpha_1, \alpha_2) and making an angle of π3\frac{\pi}{3} with the positive direction of the xx-axis, is :
  1. (1)x−3y−33+1=0x - \sqrt{3}y - 3\sqrt{3} + 1 = 0
  2. (2)3x−y+3+3=0\sqrt{3}x - y + \sqrt{3} + 3 = 0Official answer
  3. (3)x−3y+33+1=0x - \sqrt{3}y + 3\sqrt{3} + 1 = 0
  4. (4)3x−y+3−3=0\sqrt{3}x - y + \sqrt{3} - 3 = 0
