Where is the rectangle, I will help you when you show me the rectangle because I need the rectangle
Answer:
![x^2+(y+1)^2=2](https://tex.z-dn.net/?f=x%5E2%2B%28y%2B1%29%5E2%3D2)
Step-by-step explanation:
We use the formula for a circle with center at (0, -1), that goes through the (x, y) point (-1, -2):
![(x-0)^2 + (y-(-1))^2 = R^2\\Using \,\,\,point\,\,\,(-1, -2)\\(-1-0)^2+ (-2+1)^2 = 1 + 1 = 2 = R^2](https://tex.z-dn.net/?f=%28x-0%29%5E2%20%2B%20%28y-%28-1%29%29%5E2%20%3D%20R%5E2%5C%5CUsing%20%5C%2C%5C%2C%5C%2Cpoint%5C%2C%5C%2C%5C%2C%28-1%2C%20-2%29%5C%5C%28-1-0%29%5E2%2B%20%28-2%2B1%29%5E2%20%3D%201%20%2B%201%20%3D%202%20%3D%20R%5E2)
Therefore, the equation of this circle can be written as:
![x^2+(y+1)^2=2](https://tex.z-dn.net/?f=x%5E2%2B%28y%2B1%29%5E2%3D2)
