document.write( "  where m is the slope and b the y-intercept.

document.write( "2x+7y=4  Or y = (-2/7)x + 4/7   m = (-2/7)
\n" );
document.write( "y=2x+5   m = 2
\n" );
document.write( "Are they Parallel,perpendicular,or neither? Neither
\n" );
document.write( "parallel have identical slopes
\n" );
document.write( "perpendicular have slopes that are negative reciproclas of one another:
