Question

A circle is represented by the equation shown below.

(x - 5)2 + (y + 9)2 = 144

Which statement is true?

The circle is centered at (-5, -9) and has a diameter of 12.

The circle is centered at (5, -9) and has a radius of 12.

The circle is centered at (5, 9) and has a diameter of 12.

The circle is centered at (5, 9) and has a radius of 12.

Answer 1

The circle is centered at (5, -9) and has a radius of 12.

Answer 2

the general form of a circle is

(x -h)^2 + (y - k)^2 = r^2

(h, k) is the centre and r is the radius....

hopefully you can identify the values for h, k and r
