A circle with centre C has equation: x^2 + y^2 + 20x - 14 y + 49 = 0. Express the circle in the form (x-a)^2 +(y-b)^2=r^2. Show that the circle touches the y-axis and crosses the x-axis in two distinct points.

Firstly we rearrange the expression to the required form:x 2 + y 2 + 20x - 14y + 49 = 0 which gives (x + 10) 2 - 100 + (y - 7) 2 - 49 + 49 = 0 and so (x - (-10)) 2 + (y -7) 2 = 10 2 Hence a = -10, b = 7 and ...
