Correct Answer: A
Solution :
\[xy+2x+2y+4=0\] .....(i) and \[x+y+2=0\] ......(ii) from (i) and (ii), \[xy=0\Rightarrow x=y=0\] \ Vertices of triangle are \[(-2,0)\,\,(0,0)\,\,(0,-2)\] (In a right angled triangle circumcentre is mid point of hypotenuse) \ \[(-1,-1)\] is the circumcircle.You need to login to perform this action.
