Final answer:
The temperature change between noon and 6pm is -2.
Step-by-step explanation:
The temperature change between noon and 6pm can be found by subtracting the temperature at noon from the temperature at 6pm. In this case, the temperature at noon is -8 and the temperature at 6pm is -10. To find the difference, we subtract -8 from -10:
-10 - (-8) = -10 + 8 = -2
Therefore, the integer that represents the temperature change between noon and 6pm is -2.
