The line is a variable point (3,y).\r

\n" ); document.write( "\n" ); document.write( "Use the distance formula for the two points (3,y) and (2,-5).
\n" ); document.write( "\"sqrt%28%283-2%29%5E2%2B%28y-%28-5%29%29%5E2%29=3.5\"\r

\n" ); document.write( "\n" ); document.write( "\"sqrt%281%2B%28y%2B5%29%5E2%29=3.5\"\r
\n" ); document.write( "\n" ); document.write( "\"1%2B%28y%2B5%29%5E2=12.25\"\r
\n" ); document.write( "\n" ); document.write( "\"%28y%2B5%29%5E2=11.25\"-----NOT necessary to multiply the squared binomial\r

\n" ); document.write( "\n" ); document.write( "\"highlight%28y=-5%2B-+sqrt%2811.25%29%29\"-------The two possible y-coordinates; you could put into simplest radical form if needed
