Based on the graph, as temperature increases, so does the number of cases of cola sold. This suggests a positive relationship between temperature and cola sales. The information provided does not give any indication of a relationship between price and cola sales, so options C and E can be eliminated. Similarly, there is no information to suggest a non-linear relationship between temperature and cola sales, so option E can also be eliminated. Finally, the information does provide evidence of a relationship between temperature and cola sales, so option D (unrelated) can be eliminated as well. Therefore, the best answer is B (positively related).
