Points on the x-axis would have the form (x,0).
\n" ); document.write( "Use the distance formula,
\n" ); document.write( " $\"5%5E2=%28x-5%29%5E2%2B%280-4%29%5E2\"$
\n" ); document.write( " $\"25=%28x-5%29%5E2%2B16\"$
\n" ); document.write( " $\"%28x-5%29%5E2=9\"$
\n" ); document.write( " $\"x-5=3\"$ and $\"x-5=-3\"$
\n" ); document.write( " $\"x=8\"$ and $\"x=2\"$
\n" ); document.write( "(8,0) and (2,0) \n" ); document.write( "
