WebThe locus of the centre of a circle which passes through the point (a,0) and touches the line x + 1 = 0, is A Circle B Ellipse C Parabola D Hyperbola Solution The correct option is C Parabola The locus is a parabola as distance of centre from straight line = its distance from point (a,0) Suggest Corrections 0 Similar questions Q. WebOct 24, 2016 · Explanation: The standard form for the equation of a circle is: (x −h)2 + (y −k)2 = r2 where (x,y) is any point on the circle, (h,k) is the center point and r is the radius. Use the standard form to write two equations using points A and B: ( − 2 − h)2 +(0 −k)2 = r2 (5 −h)2 + (1 − k)2 = r2 Because r2 = r2, we can set the left sides equal:
