parallel lines have equal slopes and perpendicular lines have slopes which are negative inverses of each other
\n" ); document.write( ":
\n" ); document.write( "y=8x-5.......eq 1
\n" ); document.write( "y=(1/8)x+1....eq 2
\n" ); document.write( "y=-8x+2......eq 3\r
\n" ); document.write( "\n" ); document.write( " we have slopes of 8,(1/8), and -8 \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "equations 2 and 3 are perpendicular to each other since their slopes are negative inverses of each other.\r
\n" ); document.write( "\n" ); document.write( "there is no other parallel or perpendicular lines
