Question 781105: Find an equation of the circle that satisfies the stated conditions. (Give your answer in standard notation.)
Center C(−5, 6), passing through P(3, 1)

The equation of a circle centered at )
with radius 
is:
^2\ +\ (y\ -\ k)^2\ =\ r^2)
The radius is the distance from the center to any point through which the circle passes. Use the distance formula:
^2\ +\ (y_1\ -\ y_2)^2})
where )
and )
are the coordinates of the given points.
But save yourself a little work and use a modified form of the distance formula because you don't actually need the radius, you need the radius squared.
^2\ +\ (y_1\ -\ y_2)^2)
