The trend that we see in the table is that as the temperature increases, the length of the cell cycle decreases. There is an inverse relationship between these two variables. Therefore, we can predict that the length of the cell cycle increases as the temperature decreases. So, at 5$^{\circ}$C, the length of the cell cycle is longer than it is at 10$^{\circ}$C.
