How do I write the standard form equation for the circle with center (5,-4) and a point on the circle (1,1)?
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
It is
= , or
= ,
where is the radius of the circle.
To find the radius, calculate the distance from the center to the point.
It is = = = .
So, yours equation is
= .
