Answer:

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):

Therefore, the equation of this circle can be written as:

Answer:
Step-by-step explanation:
2x - y = 8
<u> x + y = - 2 </u>
3x = 6
3x /3 = 6/3 Dividing bot sides by 3 to find x.
x = 2
Plug in the value of x to find y.
2 ( 2) - y = 8
4 - y = 8
-y = 8 - 4
- y = 4
y = -4
The solution: ( 2, -4)
