An appropriate type of display to showcase the price of a house for the past 20 years would be a line graph. Line graphs are an effective way to visually represent the changes in numerical values over time. Each year would be represented on the x-axis, while the price in dollars would be plotted on the y-axis. The resulting line would show the trend of the house price over the 20-year period, allowing viewers to easily grasp the changes and fluctuations in value.
