The circle will be tangent to the line at a point with y=4.
\n" ); document.write( "The center of the circle is on the line x=-4.
\n" ); document.write( "The lines x=-4 and y=4 are perpendicular, like radius and tangent should be.
\n" ); document.write( "The segment on line x=-4 between circle center (-4,5) and the intersection with the tangent line y=4 is a radius of the circle.
\n" ); document.write( "The circle will be tangent to the line at the point (-4,4).
\n" ); document.write( "The length of the radius is 1.
\n" ); document.write( "The equation of the circle is
\n" ); document.write( " $\"%28x%2B4%29%5E2%2B%28y-5%29%5E2=1\"$
\n" ); document.write( "The circle looks like a little wheel of radius 1 (diameter=2) sitting on point (-4,4) on the horizontal line y=4. \n" ); document.write( "
