a) Select a price (P), shown on the y axis b) draw a dashed line towards the demand curve c) draw a dashed line down towards the x axis to show quantity (Q)
How to increase demand?
Reduction in price causes an increase in demand shown by a movement along the demand curve
How does demand decrease?
Increase in price causes a decrease in demand shown by a movement along the demand curve
How does demand movement occur
