Question

the points (4,-4) and (4,-6) lie on a circle with the radius of 1. what is the center point of the circle

Answer 1

The centre point is given by;
$( \frac{ x_{2}+ x_{1} }{2} , \frac{ y_{2} + x_{1} }{2} )$
=$( \frac{4+4)}{2} + \frac{-4+(-6)}{2} )$
=$( \frac{8}{2} , \frac{-10}{2} )$
=(4, -5)
