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

The correct answer is

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

Explanation:

Answer 2

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`
