5. 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
