Find the equation of a circle which touches the coordinate axes and whose centre lies on a line x-2y=3 ?
Sure, I get (x-2b-3)^2 + y^2 = b^2.
Perfect! That's the equation of the circle that touches the coordinate axes and whose centre lies on the line x-2y=3. Is there anything else I can help you with?
