Question 1024788
What is what?   Maybe you are trying to say this:
<i>What is the standard form EQUATION OF THE CIRCLE if endpoints of the diameter are (6, -2) AND (-4,4)  ?</i>

The midpoint of the two given points is are the center.  Half the distance between those two given points is the value of the radius.


{{{(6+(-4))/2=1}}} for "h"
and
{{{(-2+4)/2=2/2=1}}} for "k".



{{{r=sqrt((6-(-4))^2+(-2-4)^2)=sqrt(100+36)=sqrt(136)=sqrt(8*17)}}}



{{{highlight((x-1)^2(y-1)^2=136)}}}
