Interpret line graphs

key notes :

Understanding Line Graphs

• A line graph is used to show changes over time.
• It consists of a horizontal axis (X-axis) and a vertical axis (Y-axis).
• Data points are connected by a line to show trends.

Components of a Line Graph

• Title: Describes what the graph is about.
• X-Axis: Represents the time period (e.g., days, months, years).
• Y-Axis: Represents the values being measured (e.g., temperature, sales, population).
• Data Points: Plotted values showing trends.
• Lines: Connect the data points to show movement or trends.

How to Read a Line Graph

Identify the title to understand the graph’s topic.

Look at the X-axis and Y-axis labels to know what is being measured.

Observe the trend:

• Upward trend: Increase in values.
• Downward trend: Decrease in values.
• Flat line: No change.

Interpreting Trends and Changes

• Identify highest and lowest points to understand peaks and dips.
• Compare values at different points in time.
• Notice if the change is steady, sudden, or fluctuating.

Solving Questions Based on Line Graphs

Use the graph to answer questions like:

• What is the value at a specific time?
• How much did the value increase or decrease?
• What was the trend over a specific period?
