2. What is a Line Graph?
Graph used to represent data with an independent and dependent variable when showing changes over time
Data is plotted on the graph and connected with lines

3. When is it Used?
When you are showing changes over time

4. Real World Example
The graph shows the temperature (°F) of New York City over 6 days
Can easily see trend of data
Could be used by meteorologists

5. What Type of Data Do You Need?
Set of data- Can be a single or multiple or single set
Need key if using multiple sets of data

6. Average Time Spent Watching TV
Data Collected
Average Time Spent Watching TV
in Mrs. Ellwood's Class
Time (minutes)
Monday 37
Tuesday 40
Wednesday 39
Thursday 43
Friday 52
Saturday 83
Sunday 80

8. How We Made the Graph Draw and label a x- axis and y- axis
Create a scale on each axis
Plot your data points
Connect each point
with line segments
Give your graph a title

9. Quiz Question
A TV company wants to schedule commercials during the day kids watch the most amount of TV. Mrs. Ellwood’s class was selected to complete a survey based on how much TV they watch. Find the largest increase in time TV was watched. Then, find the percent of increase of time TV was watched.

11. How to Solve Find the largest increase in the graph.
From Friday to Saturday, the increase in time was greatest
Then find percent of increase to the nearest tenth
Difference
Original =
83-52 52 ≈
59.6%

12. Advantages of Line Graphs
Can visually see the trend of the data
Can see how data increases/decreases
Can compare two sets of data
Use a line graph with multiple sets of data

13. Disadvantages of Line Graphs
Hard to see the specific data points when the scale is large
Sometimes the scale can change the appearance of the data
