What is the standard form of the equation of a circle passes through the points (–9, –16), (–9, 32), and (22, 15)?
Let the equation be
Accordingly, we can write a system of equations.
The system therefore is
After solving, either using algebra, a C.A.S (computer algebra system) or matrices, you should get solutions of
Hence, the equation of the circle is
Hopefully this helps!
