💡 Exam Tips for Line Graphs
Drawing Line Graphs:
- Scale: Choose appropriate scales that use most of the available space
- Equal intervals: Make sure scale intervals are equal and clearly marked
- Plot accurately: Use a ruler to align points with grid lines
- Join points: Connect with straight lines (unless specifically told to use curves)
- Labels: Include clear axis labels, units, and title
- Legend: Use different colors or line styles for multiple datasets
Reading Line Graphs:
- Interpolation: Estimate values between plotted points
- Extrapolation: Predict values beyond the plotted data (extend the trend)
- Trend description: Use precise language (increasing, decreasing, constant, fluctuating)
- Rates of change: Steeper lines = faster rate of change
- Comparisons: Compare trends between different lines on multiple line graphs
