The vertices of a triangle are the points of intersection of the line $y = -x-1$, the line $x=2$, and $y = \frac{1}{5}x+\frac{13}{5}$. Find an equation of the circle passing through all three vertices.
The equation of the circle is (x + 1)^2 + y^2 = 64/25.
I don't think that is right because that circle looks like this and it doesn't go through the vertices of the triangle.
