JEE Main JEE Main 2013Straight Lines

Solution:

## Take any point B (0,1) on given line. Equation of AB' is $\, \, \, \, \, \, \, \, \, \, \, \, y-0= \frac {-1-0}{0-\sqrt 3}(x-\sqrt 3)$ $\Rightarrow \, \, \, \, \, \, \, \, -\sqrt 3y=-x+ \sqrt 3$ $\Rightarrow \, \, \, \, \, \, \, \, x- \sqrt 3 y= \sqrt 3$ $\Rightarrow \, \, \, \, \, \, \, \, \sqrt 3y=x- \sqrt 3$
