Q.

Statement–I: A variable line drawn through a fixed point cuts the coordinate axes at A and B. The locus of mid-point of AB is a circle.

Statement–II: Through 3 non-collinear points in a plane, only one circle can be drawn.

1 Both statement 1 and statement 2 are true  
2 Both statement 1 and statement 2 are false  
3 Statement 1 is true, Statement 2 is false  
4 Statement 1 is false, Statement 2 is true  

Ans.

(4)

Equation of line is x2h+y2k=1

If it passes through fixed point (x1,y1),   x12h+y12k=1
