We are asked to graph the given data of temperature vs time.
Let us first identify the points from the given data.
Temperature | Time
50° F | 6 a.m.
then the temperature rose 4° per hour for 2 hours
54° F | 7 a.m.
58° F | 8 a.m.
For the next 6 hours, it rose 1° per hour.
59° F | 9 a.m.
60° F | 10 a.m.
61° F | 11 a.m.
62° F | 12 p.m.
63° F | 1 p.m.
64° F | 2 p.m.
The temperature then stayed steady until 6 p.m.
64° F | 3 p.m.
64° F | 4 p.m.
64° F | 5 p.m.
64° F | 6 p.m.
For the next 2 hours, the temperature dropped 3° per hour.
61° F | 7 p.m.
58° F | 8 p.m.
The temperature then dropped steadily until the temperature was 56° at midnight.
56° F | 8 p.m to 12 a.m.
Now we can plot these points on the given graph.
Each vertical box corresponds to 1° F and each horizontal box 1 hour
