1. First find the slope of this line.
\n" ); document.write( "\"x-2y=24\"
\n" ); document.write( "\"-2y=24+-x\"
\n" ); document.write( "\"y=%2824-x%29%2F%28-2%29\"
\n" ); document.write( "\"y=%28x-24%29%2F2\"
\n" ); document.write( "The slope is (1/2).
\n" ); document.write( "Perpendicular lines have slopes that are negative reciprocals.
\n" ); document.write( "\"m%5B1%5Dm%5B2%5D=-1\"
\n" ); document.write( "\"%281%2F2%29m%5B2%5D=-1\"
\n" ); document.write( "\"m%5B2%5D=-2\"
\n" ); document.write( "Now use the point slope form of a line with the slope and point(1,3),
\n" ); document.write( "\"y-y%5B1%5D=m%28x-x%5B1%5D%29\"
\n" ); document.write( "\"y-3=-2%28x-1%29\"
\n" ); document.write( "\"y=-2x%2B2%2B3%29\"
\n" ); document.write( "\"y=-2x%2B5\"
\n" ); document.write( "Standard form
\n" ); document.write( "\"2x%2By=5\"
\n" ); document.write( "
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( "1.\"x+%2B+2y+=+5\"
\n" ); document.write( "2.\"3x+%2B+4y+=+1\"
\n" ); document.write( "Multiply eq. 1 by (-2) and add to eq. 2,
\n" ); document.write( "1.\"-2x+-4y+=+-10\"
\n" ); document.write( "2.\"3x%2B4y=1\"
\n" ); document.write( "\"-2x%2B3x-4y%2B4y=-10%2B1\"
\n" ); document.write( "\"x=-9\"
\n" ); document.write( "From 1,
\n" ); document.write( "1.\"x+%2B+2y+=+5\"
\n" ); document.write( "\"-9+%2B+2y+=+5\"
\n" ); document.write( "\"2y=14\"
\n" ); document.write( "\"y=7\"
\n" ); document.write( "
\n" ); document.write( "One unique solution (-9,7).
\n" ); document.write( "
