What type of graph would best present data on the average price of a single-family home over 15 years?

A line graph is the most suitable choice for presenting data on the average price of a single-family home over a 15-year period. This type of graph effectively displays trends over time, allowing viewers to easily see increases or decreases in home prices. By plotting years on the horizontal axis and the average prices on the vertical axis, a line graph visually communicates changes in values, making it straightforward for the audience to understand how the real estate market has evolved.

In contrast, a histogram would typically be used to show the distribution of data, such as how many homes fall within specific price ranges, rather than indicating changes over time. A pie chart, on the other hand, is best suited for illustrating proportions or percentages of a whole, which would not effectively convey the sequential changes in pricing data. Lastly, while a table could display the data points, it lacks the visual impact and clarity that a line graph provides in showing trends, making it less effective for this specific purpose.
