- The patient’s temperature was same at 1 p.m. and 2 p.m.
- The graph between 1 p.m. and 2 p.m. is parallel to the x-axis. The temperature at 1 p.m. and 2 p.m. is 36.5°C. So, the temperature at 1:30 p.m. is 36.5°C.
- During the following periods, the patient’s temperature showed an upward trend.9 a.m. to 10 a.m., 10 a.m. to 11 a.m., 2 p.m. to 3 p.m.
