Line & Point Interaction
The Graphing Line & Point Function Interaction is not one of the Portable Custom Interactions in the standard TAO package. It will need to be installed in a separate extension.
A Graphing Line & Point interaction is useful if you would like the Test-taker to provide an answer either with simple point coordinates, segments or lines (defined by two points), or any combination of these.
If you wish to use the Graphing Line & Point interaction, the corresponding extension will need to be installed first. See the chapter on the Extensions Manager for information on how to do this, or ask your systems administrator about the installation of this extension.
