Relating Graphs to Events ALGEBRA 1 LESSON 5-1 Which graph in Example 3 could show a car sitting at a stoplight? Graph I indicates a quantity that does not change with time. Graph II shows an increase over time. A car sitting at a stoplight would stay in the same place over time. Graph I could show a car sitting at a stoplight. 5-1

Relating Graphs to Events ALGEBRA 1 LESSON 5-1 Use the graph for questions 1–3.               1. Why does this graph not start at zero? 2. Why is the graph not a straight slanted line? 3. What does the flat part at the top of the graph represent? A person’s height is not zero when born. A straight line represents a constant rate of growth and people do not grow that way. The person has stayed the same height over a long period of time. 4. Would a horizontal line, a straight slanted line, a curve, or a jagged curve best represent the calories you burn during the day? a jagged curve 5-1
