The graph plots quantity of magazines per week on the horizontal axis, ranging from 0 to 4 in increments of 1, and quantity of burgers per week on the vertical axis, ranging from 0 to 8 in increments of 1. A line is drawn diagonally downward from 6 on the vertical axis to 3 on the horizontal axis. Another line is drawn diagonally downward, just above the first line, between 6 on the vertical axis and 4 on the horizontal axis. An arrow between the two lines reads, “Price of magazine falls.”
