Answer:



Step-by-step explanation:
The equation of the circle has the following form

The equation of the circle has the following form
We know that the circle goes through the following points
(1, 7)
(8, 6)
(7, -1).
Then we substitute the values of x and y in the equation
<u>For (1, 7)</u>


(1)
<u>For (8, 6)</u>


(2)
With these equations is enough to solve the system
(1)
(2)
Multiply the equation (1) by -8 and add it to the equation (2)
(1)
(2)
-----------------------------------------------------

Then

Finally the equation is:
