(a) The patient’s temperature was 36.5 C at 1 p.m.
(b) The patient’s temperature was 38.5 C at 12 noon.
(c) The patient’s temperature was same at 1 p.m. and 2 p.m.
(d) The temperature at 1.30 p.m. is 36.5 C. The point between 1 p.m. and 2 p.m., x-axis is equidistant from the two points showing 1 p.m. and 2 p.m. So it represents 1.30 p.m. Similarly the point on y-axis, between 36 C and 37 C will represent 36.5 C.
(e) The patient’s temperature showed an upward trend from 9 a.m. to 11 a.m.
