Line graphs - algebraic and fitted, explained by Dr Nic
Line graphs are used in algebra and in statistics and have some things in common and some differences. In this short video, Dr Nic explains these, using the example of towers made with snaplink blocks.
This video builds on the work on line graphs in "beginning algebra with tower building." ruclips.net/video/Em-xdb8Xj5o/видео.html
