Hi, I'm currently doing AS-level Maths in the UK, and I'm struggling with this question on coordinate geometry of circles:
A circle passes through the points (0, -3) and (0, 3) and has radius 5. Draw a sketch to show the two possible positions of the circles and find their equations.
Any help would be greatly appreciated!
Since we know r we get
Since we know two points that lie on the circle we can plug them in for (x,y) and this will give a system of equations in two unknowns that you can solve for h and
Can you finish from here?
