Answer:
- The center is (-1, 5) and radius is 9
Step-by-step explanation:
Given function
Put the equation into standard form:
- (x - h)² + (y - k)² = r², where (h, k) is the center, r- radius
Compete square for both x and y:
- x² + 2x + y² = 55 + 10y
- x² + 2x + 1 + y² - 10y + 25 = 81
- (x + 1)² + (y - 5)² = 9²
The center is (-1, 5) and radius is 9
