+128448 The equation is
( x - h)^2 + (y - k)^2 = r^2
Where (h, k) is the center and r is the radius
So we have
(x - (-7) )^2 + ( y - (-6) ) ^2 = 2^2
(x + 7)^2 + ( y + 6)^2 = 4
10) 3 left, 4 up
The first equation can be written as
(x - 0)^2 + (y - 0)^2 = 49 ⇒ center = (0, 0)
Moving to the left 3, we add 3 to the x coordinate of the center
Moving up 4, we subtract 4 from the y coordinate of the center
( x - 0 + 3 )^2 + ( y - 0 - 4)^2 = 49
(x + 3)^2 + (y - 4)^2 = 49
