Concurrent lines

Consider the following statements I.Number of circles touching the given three non- concurrent lines is 4. II.Number of circles passing through (1,2),(4,8) and (0,0) is one. Which of the above statement(s) is/are correct?

Statement - 1 : If non-zero numbers a , b , c are in H.P. , then the equation (x)/(a) + (y)/(b) = (1)/(c) represents a family of concurrent lines . Statement- 2 : A linear equation px + qy = 1 in x , y represents a family of straight lines passing through a fixed point iff there is a linear relation between p and q .
