Hi there! The answer is ( - 7, 5)
The standard form of the equation of a circle is the following:

In this equation r represents the radius of the circle and the point (a, b) is its centre.
Therefore, the centre of the circle

is the point ( - 7, 5).
Slope intercept: y = mx + b
Y = 5x + b
10 = -20 + b, b = 30
Equation: y = 5x + 30
Answer:
No
Step-by-step explanation:
If OR = 20,
PR = 5
