When to use a line graph?Would we use a line graphin the following situations:

To show how many people like pizza in

this class ? NO

To show how many people go to the movieson Friday? NO

To show how much it rained each monththis year? YES- because months and years deal with time.

Birthdays?

Our birthday does deal with timedoesnt it? (months/years) But, our birthday is constant,meaning it never changes.

A line graph shows change in time ,so we would not use it for this typeof graph.

Would we use a line graph to showwhen our birthdays are?

Plotting a Line graphWhen we are plotting a line graph, it is

important to read what information is oneach axis.There must be a label on each axis thatdescribes the information.Put the time on the X (horizontal axis). Putwhats changing on the Y (vertical axis).
