You can put this solution on YOUR website!
the first one is right\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "perpendicular lines have slopes which are negative reciprocals of each other
\n" ); document.write( "___ so you can just swap the x and y coefficients and change one of the signs\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "5x + 4y = ? ___ to find ? , just plug in the necessary point\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "5(-2) + 4(-5) = -30\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "5x + 4y = -30
\n" ); document.write( "
\n" );
