Question

The equation of a circle is (x - 4)2 + (y + 3)2 = 9. What are the
coordinates of the center of this circle?
. (4, -3)
• (-4,-3)
. (4,3)
• (-4, 3)

Answer 1

Coordinates of the center of the circle is (4, -3)

Step-by-step explanation:

• Step 1: Equation of a circle is of the form (x - h)² + (y - k)² = r² where (h,k) is the coordinates of the center of the circle.

Here the equation is (x - 4)² + (y + 3)² = 9

⇒ Coordinates of the center = (4, -3)
