A) \[x-y+3=0\]
B) \[x-y=0\]
C) \[x+y-1=0\]
D) line \[x+y=0\]
Correct Answer: B
Solution :
[b] Line joining \[(1,\,\,2)\] and \[(2,\,\,1)\] and line joining \[(3,\,\,4)\] and \[(4,\,\,3)\] are parallel. Also, the perpendicular bisector of any two parallel chords is axis of parabola. Hence, axis of the parabola is\[x-y=0\].You need to login to perform this action.
