Answer:
centre = (6, - 2 )
Step-by-step 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 - 6)² + (y + 2)² = 9 ← is in standard form
with (h, k ) = (6, - 2 ) ← centre
Okay. Let's start with eliminating answers. Because they're colored in dots, we know that this is a line segment. That means the domain is restricted. So not D.
A, B, C, are in correct because they're just like it's anything larger -1. This is true, but because this is a segment, then we know that it ends at some point.
So it's E.

let's multiply both the 1st and 2nd members by 12k:
(8/12K) + (3/12K) = 22 x12K
8 + 3 = 264K
<h2>K = 11/264</h2>
