\n" ); document.write( "abscissa (not abcissa) = x coordinate; ordinate = y coordinate

\n" ); document.write( "The two points are (2,4) and (-4,y). By the distance formula...

\n" ); document.write( "\"%282-%28-4%29%29%5E2%2B%284-y%29%5E2=72\"
\n" ); document.write( "\"6%5E2%2B%284-y%29%5E2=72\"
\n" ); document.write( "\"%284-y%29%5E2=36\"
\n" ); document.write( "\"4-y=6\" or \"4-y=-6\"

\n" ); document.write( "\"y=-2\" or \"y=10\"

\n" ); document.write( "ANSWERS: -2 or 10
