Question

The endpoints of a diameter of a circle are (-3,2) and (5,-6). find the center and radius of the circle. write the equation of the circle.

Answer 1

Center point is at: (-3+ X) (2+Y)
= change in range and domain
radius = (X-x)/2 or (Y-y)/2
Therefore: center is (1,-2) radius= 4
Equation: (x-1)^2+(y+2)^2=16
