First, we have to get the distance between (-3,4) and (5,-2). Use the distance formula.

Directrix (directrix):

Let's compare answers on that before we start with the points and all that.

OpenStudy (anonymous):

the distance is 10 and okay(:

Directrix (directrix):

Correct. So, the radius = ?

OpenStudy (anonymous):

5(:

Directrix (directrix):

Okay, I'm off to the grid.

OpenStudy (anonymous):

me too.

Directrix (directrix):

We need the center. Whoops. Use the midpoint formula to get the coordinates of the center of the circle.

Directrix (directrix):

@dopegyal_ What did you get for the coordinates of the center of the circle?

OpenStudy (anonymous):

Wait, so the center is (1,1)

Directrix (directrix):

Yes.

OpenStudy (anonymous):

Then the points I got were (1,6) , (1,-4) , (-4,1) (6,1)

Directrix (directrix):

Equation of circle?

OpenStudy (anonymous):

(x-1)^2 + (y-1)^2 = 25

Directrix (directrix):

Here's mine.

OpenStudy (anonymous):

Same. (:

Directrix (directrix):

Done.
