Final answer:
The center of the circle is at (2, -3), the radius is 3 units, and the diameter is 6 units. To graph the circle, plot the center point (2, -3) and draw a circle with a radius of 3 units around it.
Step-by-step explanation:
(a) The coordinates of the center of the circle are (2, -3). The equation of the circle is in the form (x - h)² + (y - k)² = r², where (h, k) are the coordinates of the center and r is the radius. In this case, (h, k) = (2, -3).
(b) The radius of the circle is 3 units. The diameter is twice the radius, so the diameter of the circle is 6 units.
(c) To graph the circle, plot the center point (2, -3) and draw a circle with a radius of 3 units around it.
