The correct expression is -16 ÷ 8.
Explanation: Since the temperature decreased by 16 degrees over 8 hours, to find the change in temperature each hour, you divide the total temperature change (-16 degrees) by the number of hours (8). This gives you the rate of temperature change per hour, which is -2 degrees per hour.
