Question

homework: graphing review
due: thursday, october 9
directions: use the information below to create a line graph using the steps discussed in class and answer the questions.
after an outbreak of influenza, a student gathered data on the number of students who became ill, until she became sick on the 14th day of her study. the information she gathered is shown below.

1. **create a line graph of the data below.

date (feb., 1996) 1 2 3 4 5 6 7 8 9 10 11 12 13 14
number of ill students 12 18 30 49 115 127 125 107 108 115 117 95 60 52

Explanation:

Step1: Set up axes

On the x - axis, label the days from 1 to 14 representing February 1 - 14, 1996. On the y - axis, choose an appropriate scale. Since the number of ill students ranges from 12 to 127, a scale like 0, 20, 40, 60, 80, 100, 120, 140 can be used.

Step2: Plot points

For each day, plot a point corresponding to the number of ill students. For example, on day 1, plot the point (1, 12), on day 2, plot (2, 18), and so on for all 14 days.

Step3: Connect points

Use a straight - edge to connect the plotted points in order from day 1 to day 14 to form the line graph.

Answer:

A line graph with x - axis labeled as days (from 1 - 14) and y - axis labeled as number of ill students, with points (1, 12), (2, 18), (3, 30), (4, 49), (5, 115), (6, 127), (7, 125), (8, 107), (9, 108), (10, 115), (11, 117), (12, 95), (13, 60), (14, 52) connected in order.
