Concept: 1 Mark
Application: 1 Mark

When we buy commodities like rice, salt, sugar, the total cost of the commodity is directly dependent on the quantity of the commodity.
For example if sugar costs Rs. 25 per kg, 2 kg will cost Rs. 50, 3 kg will cost Rs. 75, 4 kg will cost Rs. 100 etc.
When we draw a cost versus quantity graph, on plotting points we get a linear graph.
