Y=mX+b
\n" ); document.write( "(4,2) and (-4,4).
\n" ); document.write( "m=(Y2-Y1)/(X2-X1)
\n" ); document.write( "m=(4-2)/(-4-4)
\n" ); document.write( "m=2/-8
\n" ); document.write( "m=-1/4 ans. for this slope.
\n" ); document.write( "(-8,1) and (8,-3).
\n" ); document.write( "m=(-3-1)/(8+8)=-4/16=-1/4 ans. for this slope.
\n" ); document.write( "These lines are parallel because the slopes are equal.
