Talk:Demand curve

From Wikipedia, the free encyclopedia

The reference to a "downward slope" does not match the graph. Usually, an independent variable is shown horizontally (x-axis). The image in the article's top-right corner is poorly labeled and incomprehensible to all but specialists.

I teach math, I it took me quite a long time to figure out the graph. Let's make it easier for the layman, eh? --Uncle Ed 11:13, 16 July 2007 (UTC)

When describing demand & supply curves in economics we put price on the y-axis and quantity on the x-axis. For demand curves, price is the independant variable; for supply curves, quantity is the independant variable. The status quo is to put price on the left - the graphs would look much the same either way. I do, however, take umbrage at the fact that the plots on the graph are not straight lines. the labelling could do with some improvement too.--poorsod^talk 18:42, 6 January 2008 (UTC)
