A circle passes through A(-6,7) and B(1,8), radius 5. Write the general equation of the circle.

The equation of a circle is given by:
[tex](x-h)^{2} + (y-k)^{2}=r^{2}[/tex]

Taking the vector from B to A, we get:
[tex](x-(1-(-6))^{2} + (y-(8-7))^{2}=5^{2}[/tex]

Refining,
[tex](x-7)^{2} + (y-1)^{2}=25[/tex]

I hope it's right.
