The line graph illustrates Warren Buffett’s age progression over the course of 80 years, commencing from 1930.
Overall, it is immediately apparent that Buffett’s age increased in a steady and linear fashion throughout the entire time frame. His age rose proportionally with each passing year, at a constant rate of one year per year.
In 1930, Buffett’s age was recorded at zero, as this marks the year of his birth. Over the following two decades, his age progressed gradually, reaching 20 in 1950. This trend continued in the next twenty-year interval, as the figure increased to 40 by 1970. The data indicate no variation or fluctuation in the rate of change across this period.
From 1970 onwards, the upward trajectory remained consistent. Buffett’s age increased to 60 in 1990 and then to 80 in 2010, following the same uniform pattern. Each twenty-year segment reflected an identical increase of 20 years, demonstrating a perfectly linear relationship between age and time.
