Find an equation of the circle:
\n" ); document.write( "Tangent to the lines x=1, x=9, y=0
\n" ); document.write( "------------
\n" ); document.write( "There are 2 circles.
\n" ); document.write( "The centers are on the line equidistant from x=1 and x=9 ---> x = 5
\n" ); document.write( "that makes the radii 4 units.
\n" ); document.write( "===========
\n" ); document.write( "Tangent to the x-axis puts the centers at (5,4) and (5,-4)
\n" ); document.write( "
\n" ); document.write( "
\n" );
