A-level - Circle geometry - finding the equation of the circle

[@kerosene188]

Hello, I think the first question could be solved in another way:- first find the mid-point of the two points given and the gradient then find the equation of the perpendicular bisector therefore the equation of the perpendicular bisector meets the line (y=3x-12) at the centre therefore you can find the coordinates of the centre and calculate the radius so with coordinate sof the centre and the radius you find the equation of the circle

Took me some time to figure this out but it makes sense. Thanks

Maths explained I watched you since year 11. I am doing A level Maths now soon I will be year 13. I have been struggling with sketching differentiation and bearings in general ( I just can't get the notation or what the q. asks for). - Video suggestion

You could do A level maths year 1 difficult questions/topics like you did for GCSEs. Kind Regards anyways.
