1. In order to better fight cockroaches, we are going to usee a Geogebra file, and I hope that this way you are going to visualize the slope and the y-intercept of a line really fast. It’s going to be something like that:

With this information, we can hopefully kill more cockroaches:

(Extract from Wikipedia):  “Flatland: A Romance of Many Dimensions is a satirical novella by the English schoolmaster Edwin Abbott Abbott, first published in 1884 by Seeley & Co. of London. Written pseudonymously by “A Square”,[1] the book used the fictional two-dimensional world of Flatland to comment on the hierarchy of Victorian culture, but the novella’s more enduring contribution is its examination of dimensions.[2]

Book (pdf format)

Another version.

And the movie:

You can get it as a free ebook.

Y una versión en castellano: Planilandia.

Hi

0. First thing, use geogebra to correct some of the exercises from wednesday. Pay attention

17. Now we are going to  create something like this:

Send the file to me, as usual.

145. A game to practice the explicit equation (or slope-intercept) of a line. Read the instructions carefully. The aim is to kill the cockroaches with lines.

(NOTE: it’s an old game in flash, you must allow flash in the page, and maybe it will work easily in Chrome than in Firefox)
