<p>I am working on using GeoGebra for having students do graphing (for example using this app:</p>
<p><a href="http://ggbtu.be/m2820289" id="LPlnk350777"></a><a href="http://ggbtu.be/m2781237" id="LPlnk204728" title="http://ggbtu.be/m2781237

)<br>
</p>
<p>I would like to have the graph persist after submission as in the tutorial videos (</p>
<p><a href="http://www.lon-capa.org/geogebraTutorial.html" id="LPlnk679832">http://www.lon-capa.org/geogebraTutorial.html</a></p>
<p><a href="http://www.lon-capa.org/geogebraTutorial.html"></a>see especially video 3B)</p>
<p>However, I am checking the slope and x-intercept and so I don't have a submission box to store the coordinates of the points when the graph is submitted. Is there another way to keep the values, like setting them as a variable for Perl or something?</p>

<p>Thank you,</p>
