#### Explanation:

The standard form of the equation of a circle is.

#color(red)(|bar(ul(color(white)(a/a)color(black)((x-a)^2+(y-b)^2=r^2)color(white)(a/a)|)))#

where (a ,b) are the coordinates of the centre and r, is the radius.here a = -6 , b = -8 and r = 2

#rArr(x+6)^2+(y+8)^2=4" is the equation of the circle"#
