help required: law of demand

[maani]

It is a general practice to take Dependent variable on Y-Axis and Independent on X-Axis....it is a "general practice", not a "Rule"...so you can take independent variable on any of the axis...

now take a demand schedule and draw a curve taking price on x-axis and quantity demanded on y-axis...you will sill get a negative sloped demand curve...

still any confusion on queries?
