Determine which of the following equations describe a circle and which do not
1. x² + y² = 100 ; circle equation
2. x² + y² = 0 ; not a circle equation because there is no radius
3. (x - 1)² + (y + 11)² + 2 = 0 ; not a circle equation because of negative 2 radius when transposed ; (x - 1)² + (y + 11)² = -2
4. x² + (y + 2)² = 0 ; not a circle equation because there is no radius
5. (x + 4)² - (y + 6)² = 64 ; not a circle equation because of minus sign in between
