Question

Write an equation for a circle with a diameter of that has endpoints at (8,7) and (-4,-3). Round to the nearest tenth if necessary.

Answer 1

Equation of a circle: (x-h)^2 + (y-k)^2 = r^2

where (h,k) are the coordinates of the center of the circle, r = radius of circle

The radius is the midpoint of the diameter's endpoints.
