Question:
A circle has an equation of the following form.
It is a fact from geometry that given three noncollinear points—that is, points that do not all lie on the same straight line—there will be a circle that contains them. For example, the points (4, 2), (-5, -2), and (0, 3) lie on the circle whose equation is shown in the figure. Work Exercises in order, to find an equation of the circle passing through the points
Let x = 2 and y = 1 in the general equation x2 + y2 + ax + by + c = 0 to find an equation in a, b, and c.
