The line `x+y=k` will cut the circle `x^2 + y^2 - 4x - 6y + 5 = 0` at two distinct points if (A) `klt1` (B) `klt1` or `Kgt9` (C) `1ltklt9` (D) none of these

If the line y=mx-(m-1) cuts the circle x^(2)+y^(2)=4 at two real and distinct points then

The line 3x+5y+9=0 w.r.t.the circle x^(2)+y^(2)-6y+5=0 is

The line lambda x+mu y=1 is a normal to the circle 2x^(2)+2y^(2)-5x+6y-1=0 if

The line x+2y+a=0 intersects the circle x^2+y^2-4=0 at two distinct points A and B. Another line 12x-6y-41=0 intersects the circle x^2+y^2-4x-2y+1=0 at two distincts points C and D. The value of 'a' so that the line x+2y+a=0 intersects the circle x^2+y^2-4=0 at two distinct points A and B is
