Question

(x + 3)2 + (y – 5)2 = 1

What would be the center of this?

Answer 1

(- 3, 5 )

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

(x + 3)² + (y - 5)² = 1 ← in standard form

with centre = (h, k) = (- 3, 5 )
