Justify each step used to simplify the expression
1. 3x + 2y - 2x + 2 = 3x - 2x + 2y + 2
2. = (3x – 2x) + 2y + 2
3. = (3 - 2)x + 2y + 2
4. = x + 2y + 2

Which equation represents a circle with a center at (–3, –5) and a radius of 6 units? (x – 3)2 + (y – 5)2 = 6 (x – 3)2 + (y – 5)2 = 36 (x + 3)2 + (y + 5)2 = 6 (x + 3)2 + (y + 5)2 = 36
