You can put this solution on YOUR website!
I'll do the first, you do the next one the same way.
\n" ); document.write( "\"5x%2B4y=8\"
\n" ); document.write( "\"4y=-5x%2B8\"
\n" ); document.write( "\"y=-%285%2F4%29x%2B2\"
\n" ); document.write( "The slope of this line is \"m=-5%2F4\".
\n" ); document.write( "Now find the slope of the second line.
\n" ); document.write( "If they're parallel,
\n" ); document.write( "\"m%5B1%5D=m%5B2%5D\"
\n" ); document.write( "If they're perpendicular to each other,
\n" ); document.write( "\"m%5B1%5D%2Am%5B2%5D=-1\"
\n" ); document.write( "Else choose neither.
\n" ); document.write( "
\n" );
