Answer:

The centre (a,b) = (-5,-1) and

radius r = 2

Step-by-step explanation:

[tex] {(x + 5)}^{2} + {(y + 1)}^{2} = {2}^{2} [/tex]

Ccompare this with general equation of a circle, where (a,b) is the centre of the circle and r is the radius.

[tex] {(x - a)}^{2} + {(y - b)}^{2} = {r}^{2} [/tex]

Hence,

The centre (a,b) = (-5,-1) and

radius r = 2
