Find the slopes of the 2 lines.
\n" ); document.write( "slope m = diffy/diffx
\n" ); document.write( "m1 = (8-6)/(3-0) = 2/3
\n" ); document.write( "----------------------
\n" ); document.write( "Find the other slope the same way.
\n" ); document.write( "If the slopes are the same (2/3) they're parallel.
\n" ); document.write( "If the 2nd slope is the negative inverse (-3/2) they're perpendicular.
\n" ); document.write( "If neither, they're neither.
\n" ); document.write( "
