\
Graph the circle with center at (3, -2), which also passes through the point (0, 2). Label the center and at least four points on the circle. Write the equation of the circle.
\Step 1:
\The center of the cirle is
.
The circle passes through the point is
.
The distance from center to any point on the circle is radius.
\



.
The radius of the circle is
.
Step 2:
\The standard form of circle equation is
, where
is the center of the circle and
is radius.
Substitute center
and
in standard form of circle equation.
