    I have attached an image of the question. I have begun the question by completing the square on the equation of the circle. Thus with the centre point, I have presumed that line A would cross this point as I know the normal always crosses the centre of the circle. I have made the assumption that line B would be the perpendicular line to line A, but I don't still think I have enough information to give co-ordinates for point A and B. Any help is much appreciated.

    Anyone? Note: I have added the lines and grid myself as well as the centre point which could be wrong.

    You know the centre

    You know the radius

    So the distance from the centre to A is less than 5 and the distance from the centre to B is more than 5

    Does that help at all

    Have you drawn the axis on?
    The 2nd line should =-1 not 12
