Line Graph Legends

What does a point on a line graph represent?

• The time of day

• A specific value at a certain time

• The title of the graph

• The average of all data points

If the line on the graph is moving upwards from left to right, what does that indicate about the values?

• The values are decreasing

• The values are staying the same

• The values are increasing

• The values cannot be determined

What should you do first when reading a line graph?

• Look at the title

• Check the labels on the axes

• Find the highest point on the graph

• Count the number of points on the graph

If a line graph shows the temperature over a week, what would the line going down indicate?

• The temperature is rising

• The temperature is the same

• The temperature is falling

• The days are getting longer

How can you tell which day had the highest temperature if you are looking at a line graph of temperature over a week?

• Look for the longest line

• Look for the line that is the most vertical

• Look for the highest point on the graph

• Look for the point furthest to the right

What does the horizontal axis (x-axis) usually represent in a line graph?

• Time or categories

• Temperature

• Speed

• Height

What does the vertical axis (y-axis) usually represent in a line graph?

• Time or categories

• The value of what is being measured

• Distance

• Weight

If a line graph has multiple lines, what does each line typically represent?

• Different units of measurement

• The same data repeated

• Different sets of data or categories

• Errors in the data

How can you compare two different sets of data on the same line graph?

• By looking at the color or style of the lines

• By counting the number of points

• By measuring the length of the lines

• By the position of the title

What should you do if you don't understand the scale on a line graph?

• Guess the values

• Look for a key or legend

• Ignore the scale

• Only look at the pictures
