Straight lines

Ans is 1

@sourabhakallapur
If both perpendicualr to same line that means both are parallel. So both hv same slopes

@ashishdeosingh but can we equalize coefficients of x and y as they are parallel

@sourabhakallapur
We need to get same slope not the same coefficients so for parallel you should equate (coefficient of x)/(coefficient of y) of both lines and not necessarily the coefficients

@vedantzope ok thanks
