Answer: The standard equation of the circle centered at (h,k) is given:
where r is the radius and (h,k) the center.
If the center is the origin then the equation will be:
where r is the radius.
If a line pas through the points (X1,Y1) and (X2,Y2),its equation is:

Where: m=(Y2-Y1)/(X2-X1) is the slope of the line.
