Answer to Problem 16PPS
For graph A:
For graph B:
Explanation of Solution
Given: Suppose Isabel decide to save
For the graph A
Slope is
The slope of the line is
Now
Thus
Thus the equation of the line for the graph A is
Similarly
For the graph B
The slope of the line is
Now
Thus
Thus the equation of the line for the graph B is
