Say you want to graph x>4.\r
\n" ); document.write( "\n" ); document.write( "You plot 4 on your number line and draw a line extending up the number line with an arrow on the end pointing to infinity. When you plot 4 use an empty dot, a little circle.\r
\n" ); document.write( "\n" ); document.write( "If x is greater than or equal to 4, have a filled in dot at 4 and the line with the arrow pointing up the line.\r
\n" ); document.write( "\n" ); document.write( "Do you need to graph a compound inequality?
\n" ); document.write( "Say x > 4 and x < 6\r
\n" ); document.write( "\n" ); document.write( "Plot 4 with line and an arrow up the line and 6 with a line and an arrow down the line.\r
\n" ); document.write( "\n" ); document.write( "Again, use the little circle to plot the numbers on the line. Draw the line between 4 and 6 a bit heavy on the paper so your teacher can tell that section from the rest of the number line.\r
\n" ); document.write( "\n" ); document.write( "If you want to graph 4 < x or 6 > x, plot 4 with an arrow pointing down and 6 with an arrow pointing up the number line.\r
\n" ); document.write( "\n" ); document.write( "Just remember, fill in the dot if there's an \"or equal to\" in the inequality but not if its just < or >. \n" ); document.write( "
