A circle with center at (a, b) and radius r, has an equation
(x - a)^2 + (y - b )^2 = r^2
1. Center (-2, -5) and radius 1 has equation (x + 2)^2 + (y + 5)^2 = 1
2. Center (5, 6) and radius 3 has the equation (x - 5)^2 + (y - 6)^2 = 9
(x - a)^2 + (y - b )^2 = r^2
1. Center (-2, -5) and radius 1 has equation (x + 2)^2 + (y + 5)^2 = 1
2. Center (5, 6) and radius 3 has the equation (x - 5)^2 + (y - 6)^2 = 9
-
1. (x+2)squared + (x+5)squared = 1
2. (x-5)squared + (x-6)squared = 9
2. (x-5)squared + (x-6)squared = 9
-
(x+2)²+(x+5)²=1²
and
(x-5)²+(x-6)²=3²
and
(x-5)²+(x-6)²=3²
