Answer
Usually, when we draw any graph, the scale on which the graph is measured starts from zero on the y-axis. However, under the situations when the data to be plotted on graph starts from a value which is far above zero, results in the problem of shortage of space on graph. To overcome this problem of shortage of space, a false base line is plotted. False base line is a line which is drawn to grasp the attention of the reader on the fluctuations which usually remains unnoticed.

How does an increase in the number of firms in a market affect the market supply curve?
Equilibrium price never changes in a situation of perfectly elastic supply, no matter what the demand is. Is it true? Explain diagrammatically.
Supposing the initial demand was $100$ units. With the rise in price by $₹5,$ the quantity demanded decreases by $5$ units. Elasticity of demand is $1.2.$ Find out the price before the change in demand.
