Step 1:
\Graph the circle (x + 2)^2 + (y + 1)^2 = 32. Label the center and at least four points on the circle.
The circle equation is .
The standard form of circle equation is , where
is the center of the circle and
is radius.
Compare the circle equation with standard form.
\Here and

Solution:
\Graph of the circle :
\
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.
The circle equation is .
