Reading Line Graphs
Reading Values
- Locate the point: Find the time on x-axis
- Trace vertically: Go up to the line
- Read horizontally: Go across to the y-axis to read the value
Identifying Trends
- Increasing: Line goes up from left to right
- Decreasing: Line goes down from left to right
- Constant: Line is horizontal (no change)
- Fluctuating: Line goes up and down
Finding Maximum and Minimum
- Maximum: Highest point on the graph
- Minimum: Lowest point on the graph
- Local peaks: Points higher than neighboring points
- Local valleys: Points lower than neighboring points
