A) \[x+2y=0\]
B) \[2x+y=0\]
C) \[x-y=0\]
D) None of these
Correct Answer: C
Solution :
Since equation of diagonal \[11x+7y=9\]does not pass through origin, so it cannot be the equation of the diagonal OB. Thus on solving the equation AC with the equations OA and OC, we get \[A\left( \frac{5}{3},-\frac{4}{3} \right)\] and \[C\,\left( \frac{-2}{3},\,\frac{7}{3} \right)\].You need to login to perform this action.
