You can put this solution on YOUR website!
Remember that the slopes of perpendicular lines are the negative reciprocal of each other.\r
\n" ); document.write( "\n" ); document.write( "Since all of the possible answers are in the slope-intercept form y = mx+b, you can compare the slopes of the answers to find two slopes that are negative reciprocals.\r
\n" ); document.write( "\n" ); document.write( "b) \"3x-5%2F3\" The slope is 3
\n" ); document.write( "c) \"%28-1%2F3%29x%2B5%2F3\" The slope is \"-1%2F3\", the negative reciprocal of 3
\n" ); document.write( "
\n" );
