How do you write an equation for a circle with radius of 2 with it's centre being (-6,-8)?

"Suppose that I don't have a formula for #g(x)# but I know that #g(1)
= 3# and #g'(x) = sqrt(x^2+15)# for all x. How do I use a linear approximation to estimate #g(0.9)# and #g(1.1)#?"

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"#
