A) \[x-y=0\]
B) \[(x+y)(a+b)=2ab\]
C) \[(lx+my)(a+b)=(l+m)\ ab\]
D) All of these
Correct Answer: D
Solution :
Intersection point of the line is \[\left( \frac{ab}{a+b},\frac{ab}{a+b} \right)\], which is satisfying all the equations given in options (a), (b) and (c). Hence (d) is correct.You need to login to perform this action.
