50 points and brainliest!
write the general equation for the circle that passes through the points: (1, 7) (8, 6) (7, -1)

.

Step-by-step explanation:

Let the general equation of the circle be .

Each of the points must satisfy this equation.

We substitute (1,7) to get:

.

.

.

We substitute (8,6) to get:

.

.

.

We substitute (7,-1) to get:

.

.

.

Solving equations 1, 2, and 3 simultaneously gives:

Hence the equation of the circle is

.

.

#15. square

step-by-step explanation:

because quadrilatural (idk how to spell it) means somthing that is not 3d or like, equal sides (or somthing like that   you know what i meanz)

hope this halps!

bai!
