#### Answer:

This is the general equation of a circle centred at

#### Explanation:

Any circle centred at

Therefore this is the general equation of a circle centred at

The graph will be the union of the following 2 semi-circles :

graph{2+sqrt((49-(x+5)^2) [-20.27, 20.27, -10.14, 10.12]}

graph{2-sqrt((49-(x+5)^2) [-20.27, 20.27, -10.14, 10.12]}

and it should look like this

graph{x^2 +10x + y^2 - 4y - 20 = 0 [-20.27, 20.27, -10.14, 10.12]}
