Question 1021432
Find the equation of the circle which passes through the points (1,-2), (5,4) & (10,5).
---------
Label the points.
Find the equation of the circle which passes through the points A(1,-2), B(5,4) & C(10,5).
--------
Find the perpendicular bisectors of AB and BC.
Then find the intersection of the bisectors.  That's the center of the circle.
Call it (h,k)
---
The distance from the center to any point A, B OR C, is the radius.
---
{{{(x-h)^2 + (y-k)^2 = r^2}}} is the circle.
