Statement 1 : The equation `x^2+y^2-2x-2a y-8=0` represents, for different values of `a ,` a system of circles passing through two fixed points lying on the x-axis. Statement 2 : `S=0` is a circle and `L=0` is a straight line. Then `S+lambdaL=0` represents the family of circles passing through the points of intersection of the circle and the straight line (where `lambda` is an arbitrary parameter).
