perpendicular lines have slopes that are inverses.
\n" ); document.write( "\"5%2F1\"
\n" ); document.write( "\"-1%2F5\"
\n" ); document.write( "These slopes are perpendicular.
\n" ); document.write( "Parallel lines have the same slope.\r
\n" ); document.write( "\n" ); document.write( "first solve the equations for y\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "a. \"y=2x%2B5\"
\n" ); document.write( "slope is \"2%2F1\"
\n" ); document.write( "\"2x%2By=9\"
\n" ); document.write( "\"y=-2x%2B9\"
\n" ); document.write( "slope is \"-2%2F1\"
\n" ); document.write( "The slope arent the same or inverses.
\n" ); document.write( "neither\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "b.\"3x%2B4y=7\"
\n" ); document.write( "\"4y=-3x%2B7\"
\n" ); document.write( "\"y=%28-3%2F4%29x%2B%287%2F4%29\"
\n" ); document.write( "slope is \"-3%2F4\"
\n" ); document.write( "\"4x=3y-8\"
\n" ); document.write( "\"4x%2B8=3y\"
\n" ); document.write( "\"%284%2F3%29x%2B%288%2F3%29=y\"
\n" ); document.write( "The slope is \"4%2F3\"
\n" ); document.write( "These slopes are inverses.
