Draw two perpendicular lines to represent the axes. The vertical axis (Y-axis) represents the price of the product, and the horizontal axis (X-axis) represents the quantity demanded. Plot a demand curve that is relatively steep. This steepness indicates inelastic demand, meaning that changes in price lead to smaller changes in quantity demanded. In the context of PepsiCo, this reflects the scenario where, despite price changes, the quantity of PepsiCo products demanded by brand-loyal consumers does not change significantly. The LaTeX code for a basic representation (note that actual graph plotting is not possible within LaTeX here, but this provides a structure for how the graph can be conceptualized)
