Question

Write the general equation for the circle that passes through the points: (-1, 2) (4, 2) (- 3, 4) you must include the appropriate sign (+ or -) in your answer. do not use spaces in your answer. x 2 + y 2 -3 x -13 y -40 = 0

Answer 1

The center is (3/2, 13/2) and the square of the radius is 53/2, so the standard form equation is
(x -3/2)^2 +(y -13/2)^2 = 53/2

In general form, this is
x^2+y^2-3x-13y+18=0
