Question

A circle has a diameter with endpoints (-7, -1) and (-5, -9).

What is the equation of the circle?


r2 = (x + 6)2 + (y + 5)2
r2 = (x + 4)2 + (y + 1)2
r2 = (x + 6)2 + (y - 1)2
r2 = (x + 4)2 + (y + 5)2

Answer 2

find the coordinates of the center
if endpoints are given as (x1,y1) and (x2,y2) then midpoint=(x1+x2/2,y1+y2/2)
