The temperature increased from 9 a.m. to 11 a.m. and from 12 p.m. to 1 p.m, as the line on the graph is going up during these intervals. The temperature seems to remain relatively stable or decrease slightly during the other time intervals. From 9 a.m. to 11 a.m., the temperature increases from around 56°F to around 63°F, and from 12 p.m. to 1 p.m., the temperature increases from around 64°F to around 68°F. During the other time periods, the temperature either remains constant or decreases, so the only hours during which the temperature was increasing were 9 a.m. to 11 a.m. and 12 p.m. to 1 p.m.
