Online Quiz: Reading Line Graphs to Show Change

📚 Quick Study Guide

• 📈 Line Graphs: Visual representations of data that changes over time.
• xAxis X-axis (Horizontal): Usually represents the time period (days, months, years).
• 📊 Y-axis (Vertical): Represents the quantity being measured (temperature, sales, etc.).
• 🧭 Data Points: Each point on the line represents a specific data value at a specific time.
• 📉 Trends: Look for upward or downward slopes to identify increasing or decreasing trends.
• ➕ Interpreting Change: The steeper the slope, the faster the rate of change.
• 💡 Tips: Always read the labels on both axes carefully to understand what the graph is showing.
