A) \[y-x+1=0\]
B) \[y-x-1=0\]
C) \[y-x+2=0\]
D) \[y-x-2=0\]
Correct Answer: B
Solution :
The line perpendicular to the line \[x+y+1=0\] is \[y-x+\lambda =0\]. Also, it passes through the point (1, 2); \[\therefore \] \[\lambda =-1\]. Hence, required line is\[y-x-1=0\].You need to login to perform this action.
