The graph that shows the relationship between the number of days the Girl Scout has been selling cookies and the total number of boxes remaining is a line graph. The line graph has two axes: the x-axis, which represents the number of days, and the y-axis, which represents the number of boxes remaining. The points on the line graph represent the number of boxes remaining after a certain number of days.
The first point on the line graph is (0, 25). This point tells us that the initial number of boxes is 25. The second point on the line graph is (1, 21). This point tells us that after 1 day, the number of boxes remaining is 21. The third point on the line graph is (3, 19). This point tells us that after 3 days, the number of boxes remaining is 19. The fourth point on the line graph is (7, 13). This point tells us that after 7 days, the number of boxes remaining is 13.
The line graph that passes through the points (0, 25), (1, 21), (3, 19), and (7, 13) is the only line graph that passes through all of these points. Therefore, the correct graph is a coordinate plane with the x axis labeled time in days and the y axis labeled number of boxes, with a line that passes through the points 0 comma 25, 1 comma 21, 3 comma 19, and 7 comma 13.
