Question

endpoints of a diameter (-7,8),(-3,-2). Find the equation for the circle

Answer 1

I need some help to figure this out.

Answer 2

Well you need origin and the radius so you can plug it in to the equation of a circle
To find the origin use the midpoint theorem...
To find the radius use distance formula of the points and divide by two.
Need me to evaluate?

Answer 3

Yes please.

Answer 4

Formula of a circle in standard form... (x-h)^2+(y-k)^2=r^2... Where (h,K) is the origin and r is the radius..
Midpoint formula is \[(\frac{ x _{1} +x_2 }{ 2 }, \frac{ y_1+y_2 }{ 2 })\]
Distance Formula is http://cs.selu.edu/~rbyrd/math/distance/ (too lazy to type it out

Answer 5

So I came up with 8. Is that correct?

Answer 6

the anser is the whole equation?

Answer 7

Ok. I got 5 for the x and 3 for y. So the equation should be (x+5)+(y-3).

Answer 8
