ALGEBRA 1 LESSON 5 -1 Relating Graphs to Events 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

ALGEBRA 1 LESSON 5 -1 Relating Graphs to Events Use the graph for questions 1– 3. 1. Why does this graph not start at zero? A person’s height is not zero when born. 2. Why is the graph not a straight slanted line? A straight line represents a constant rate of growth and people do not grow that way. 3. What does the flat part at the top of the graph represent? 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
