# Maths A level Question Help watch

1. 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.

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

You know the centre

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
4. Have you drawn the axis on?
The 2nd line should =-1 not 12
5. Have you drawn the axis on?
The 2nd line should =-1 not 12 - I think
