Question

Callie and Joe are examining the population data in the graphs below for a history report. Their comments are as follows:

Callie: It looks like the U.S. population grew the same amount as the world population, but that can’t be right, can it? Joe: Well, I don’t think they grew by the same amount, but they sure grew at about the same rate. Look at the slopes

Answer 1

Answer: The slopes are not the same

Step-by-step explanation: Looking at the y-axis, we see that the intervals are not the same. Drawing a line of best fit and solved for slope using rise/run, we can prove that the world population grew significantly faster than the American population.
