To describe: The error in interpreting the slope in the context of the situation.

Answer to Problem 11E
Given slope is correct balance after 7 years will be 170.
Explanation of Solution
Given Information: - Given a linear graph.
Calculation:
As the line in the graph is passing through the points
Therefore, slope of line
The given slope is correct, let’s find the error in interpreting the slope.
Here, slope does not show the balance after 7 years, slope show how much will the balance grow in one year.
Now multiply the slope by 7 and we can find the balance grow in 7 years. Balance at the beginning was $100. After 7 years the balance.
Thus, slope is correct balance after 7 years will be 170.
