Practice Problem 1: The following table shows the quantity of oxygen gas that can be obtained from the

electrolysis of various quantities of water. Make a line graph of the data:

Determine what variable to place on the x-axis and the y-axis.

Label each axis in the provided text boxes.

Scale each axis appropriately. Fill in scale values in the provided text boxes.

Title your graph in the provided text box.

Plot points as accurately as possible. You have been provided with a couple of points to get started
copy and paste these to create as many points as you need. Drag and drop them onto your graph.
Draw lines to connect the points. You can draw a line by going to Insert

Line

Line. You can

adjust the weight of your line by selecting it and adjusting line weight in the toolbar.

Identify factors that might cause a change in shape of the graph.

Use your graph to estimate the total distance traveled by 10:30 am. Can you be absolutely certain of this

value?

How far did Fred travel in the first hour of his trip? How far did Fred travel in the last hour of his trip?

Suggest a possible explanation for this difference.

Practice Problem 3: The table below shows the amount of rainfall (inches) in a tropical area on the first
day of each month. Data was collected for two consecutive years. Prepare a graph of the data, placing the

data from both years on the same graph:

Determine what variable to place on the x-axis and the y-axis.

Label each axis in the provided text boxes.

Scale each axis appropriately. Fill in scale values in the provided text boxes.

Title your graph in the provided text box.
