Need help please:

(3,0) (7,6)

(x-7)2 + (y-6)2 = 7(2)

(x-7)2 + (y-6)2 = 49

Having difficulty with this problem.Can someone help?

You don't say what the actual problem is.

I see the resemblance to finding the equation of a circle??

What are you trying to find?

It says to write an equation of a circle with diameter

Is A at (3,0) and B at (7,6) ?

if so then the center is halfway between.

Xc = (3+7)/2 = 5

Yc = (0+6)/3 = 3

so of form

(x - 5)^2 + (y - 3)^2 = r^2

but r is half the length of AB

AB^2 = 4^2 + 6^2 = 16+36 = 52

AB = 7.21

(1/2) AB = r = 3.61

r^2 = 13

so in the end

(x - 5)^2 + (y - 3)^2 = 13

6 = x + 2
