The law of demand can be explained with the help of example and diagram.

Yes, I agree with this statement.

Reasons:

Meaning: -The Law of demand establishes the functional relationship between the Price of a commodity and the quantity of that commodity demanded at different prices, assuming other factors remaining constant.
We can explain this law with the help of a schedule and a diagram.

Price (Rs.)
Quantity Demanded
1
2
3
4
5
50
40
30
20
10
          
The Schedule shows that with an increase in Price the quantity demanded is decreasing. It indicates inverse relationship between the two variables price and quantity demanded. When the price is Re. 1 the consumer demand 50 units and when the price rises to Rs. 5 he demands the least that is 10 units.



In the above diagram X-axis represents quantity demanded and Y-axis represents price. Various points from the schedule are plotted on the graph, joint those points we will be getting demand curve. DD is the demand curve which slopes downward from left to right indicating inverse relationship between price and Quantity demanded. This happens when the price is more, demand is less and when price is less, and demand is more.
