Write the general equation for the circle that passes through the points (1, 1), (1, 3), and (9, 2).

You must include the appropriate sign (+ or -) in your answer. Do not use spaces in your answer.
8x^2 + 8y^2__x__y=0

Step-by-step explanation:

The general equation of the circle is

.

Putting in the point , we get:

or

.

For the point we get:

or

Finally, for the point we get:

or

Thus, we have three equations and three unknowns:

.

and their solutions are (Used Cramer's rule )

Thus, the equation of the circle is

$8

step-by-step explanation:

it is pretty much backwards.

you take the 4x2 multiply that, and that is = $8
