Answer:

Step-by-step explanation:
You are given four time and temperature points:
(time, temperature) ∈ {(12 am, 60°), (2 am, 42°), (6 am, 42°), (8 am, 67°)}
The graph below shows these plotted, using x=0 as midnight and hours on the horizontal axis. Degrees are on the vertical axis.
Nothing in the problem statement suggests that these points should be connected with straight lines. <em>We have added lines here</em>, partly to show what it means that the temperature stayed the same for 4 hours, and partly to make the temperature points more visible.
A graph of the temperatures given in the problem statement would show the given points with a horizontal lines connecting the points at 2 am and 6 am. You may or may not want to add some connection between the other dots, depending on the expected use of the graph.
