You can put this solution on YOUR website!
If the point is one the y-axis, your domain would be x = 0.
\n" ); document.write( "(0,y) and (3,4) are your points
\n" ); document.write( " $\"distance+=+sqrt%28%28x2+-+x1%29%5E2+%2B+%28y2+-+y1%29%5E2%29\"$
\n" ); document.write( " $\"5+=+sqrt%28%283+-+0%29%5E2+%2B+%284+-+y%29%5E2%29\"$
\n" ); document.write( " $\"25+=+%283%29%5E2+%2B+%284+-+y%29%5E2\"$
\n" ); document.write( " $\"25+=+25+-+8y+%2B+y%5E2\"$
\n" ); document.write( " $\"0+=+y%5E2+-+8y\"$
\n" ); document.write( " $\"0+=+y%28y+-+8%29\"$
\n" ); document.write( "y = 0 and y = 8
\n" ); document.write( "So: (0,0) and (0,8)
\n" ); document.write( "0 is not positive nor negative
\n" ); document.write( "Answer: (0,8) \n" ); document.write( "

\n" );
