You can put this solution on YOUR website!
The line \"+x+=+4+\" is a vertical line through ( 4,0 )
\n" ); document.write( "For every \"+y+\" value on this line, is is still true
\n" ); document.write( "that \"+x+=+4+\"
\n" ); document.write( "----------------
\n" ); document.write( "Any line perpendicular to this line will
\n" ); document.write( "be a horizontal line with the equation \"+y+=+k+\"
\n" ); document.write( "You are given the point ( 2,5 ) that this line passes
\n" ); document.write( "through, so \"+k+=+5+\", and the equation
\n" ); document.write( "of this perpendicular line is \"+y+=+5+\"
\n" ); document.write( "
\n" ); document.write( "
\n" );
