A) \[(-1,\ -2)\]
B) (1, 2)
C) \[(-2,\ -3)\]
D) (2, 3)
Correct Answer: A
Solution :
\[(a-2b)x+(a+3b)y+3a+4b=0\] or \[a\text{ }(x+y+3)+b\text{ }(-2x+3y+4)=0\], which represents a family of straight lines through point of intersection of \[x+y+3=0\]and \[-2x+3y+4=0\]i.e, (? 1, ? 2). Trick: Point (-1, -2) satisfies the given equation of straight line.You need to login to perform this action.
