Find the equation of a circle which touches the coordinate axes and whose centre lies on a line x-2y=3 ?
The equation of the line is x-2y=3.
Great! So, we know that the centre (a,b) of the circle lies on this line, which means that it can be expressed as a = 2b + 3. Now, all we need to do is find the radius of the circle. Can you tell me how we can do that?
