Determine which of the following line, if any, are parallel or perpendicular.
\n" ); document.write( "Line a: 6x+2y=5
\n" ); document.write( "y = -3x + (52)
\n" ); document.write( "slope = -3
\n" ); document.write( "-----------------------\r
\n" ); document.write( "\n" ); document.write( "Line b: y=1/3x-4
\n" ); document.write( "slope = 1/3
\n" ); document.write( "-------------------------\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Line c: y=-3x+5
\n" ); document.write( "slope = -3
\n" ); document.write( "-------------------
\n" ); document.write( "lines a and b are perpendicular because the product of their
\n" ); document.write( "slopes is -1
\n" ); document.write( "-----------
\n" ); document.write( "lines b and c are perpendicular for the same reason
\n" ); document.write( "---------------
\n" ); document.write( "lines a and c are parallel because their slopes are equal.
