Answer:
( x + 3)² + ( y + 7)² = 361
Step-by-step explanation:
The equation of a circle written in standard form is ( x – h)² + ( y - k)² = r². The center is (h, k) and the radius is r.
With the given information of center (-3, -7) and radius 19, we get
[ x – (-3)]² + [ y - (-3)]² = (19)²
( x + 3)² + ( y + 7)² = 361

24x + 36 - 10x + 12 =
14x + 48 =
2(7x + 24)
