Question

What’s the correct answer for this?

Answer 1

(x + 5)² + (y - 7)² = 13

Explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

Here (h, k) = (- 5, 7) and r =
`√(13)` , thus

(x - (- 5))² + (y - 7)² = (
`√(13)` )² , that is

(x + 5)² + (y - 7)² = 13 ← equation of circle
