Question

The circle below is centered at the point (4,-3) and has a radius of length 3 what is it’s equation?

Answer 1

Hi there!

The standard form of the equation of a circle is:
$(x - a) {}^{2} + (y - b) {}^{2} = r {}^{2}$

With (a, b) representing the centre and r representing the radius of the circle.
Since the centre of the circle is (4, -3) and the radius is 3, we get the following equation:

$(x - 4) {}^{2} + (y + 3) {}^{2} = 9$

Answer 2

Answer:

The correct answer is

(X+3)2 + (y-4)2 = 9
