    <dc:creator>keithpeter</dc:creator><description><![CDATA[Three sides introducing (x,y) notation and the patterns associated with a straight line graph. Some work on coordinate geometry (i.e. find the coordinate to complete the rectangle/isosceles triangle/kite). Plotting from formulas for simple cases. Idea that the constant in the y=3x +1 type formula controls how far up the Y axis the line is...

Graph grids with points and labels produced using pyxplot 8.01, and nice they look as well. Page about using this software coming soon.]]></description>
