(a) -3/2
\n" ); document.write( "If you have a line with slope \"+m+=+2%2F3+\",
\n" ); document.write( "any line perpendicular to this one
\n" ); document.write( "will have slope \"+-%281%2Fm%29+=+-%281%2F%28%282%2F3%29%29%29+\"
\n" ); document.write( "\"+-%281%2F%28%282%2F3%29%29%29+=+-%283%2F2%29+\"
