Answer:
Correct option is C)
2x
2
−xy−y
=0
By factorization,
(2x+y)(x−y)=0
Since, we have given that combined equation of the pair is parallel to 2x
So combined equation will be,
(2x+y+k
1
)(x−y+k
)=0
This equation satisfies (1,0)
(2×1+0+k
)(1−0+k
k
=−1,k
=−2
Put k
,k
in main equation and get combined equation as
−4x+y+2=0
