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
__
AB

  • Geometry -

    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
