...what is it that you need help in in parallel and perpendicular lines?\r
\n" ); document.write( "\n" ); document.write( "Well, here is what I know. I hope this helps.
\n" ); document.write( "Without graphing, we can know whether 2 lines are parllel and perpendicular.
\n" ); document.write( "Parallel lines have the same slopes.
\n" ); document.write( "for example, y=2x+4 and 2y-4x=6
\n" ); document.write( "if we simply and put these two equations in y=mx+b form, where m is the slope, we can know that 2 is the slope.\r
\n" ); document.write( "\n" ); document.write( "These are parallel lines.\r
\n" ); document.write( "\n" ); document.write( "The slope of perpendicular lines are opposite of the reciprocal of each other.
\n" ); document.write( "For example, y=-1/2x+3 and y=2x+6
\n" ); document.write( "The statement above can be expressed in the following equation.
\n" ); document.write( "(m1)(m2)=-1
\n" ); document.write( "the 2 ms are the slopes.
\n" ); document.write( "They multiplied to become -1.
\n" ); document.write( "lets check the example.
\n" ); document.write( "(-1/2)(2)=-1
\n" ); document.write( "Check. ^^ \n" ); document.write( "
