2. Relating Graphs to Events ALGEBRA 1 LESSON 5-1 1. (4, –2) is point C 2. (4, 3) is point D 3. (2, –4) is point E 4. (–2, 1) is point A 5. B coordinates: (0, 0) 6. F coordinates: (–4, –2)‏ 7. G coordinates: (–3, 3)‏ Solutions

3. Relating Graphs to Events Describe what this graph shows by labeling each part. ALGEBRA 1 LESSON 5-1

5. Relating Graphs to Events Sketch a graph of the altitude of a pelican, from take off from shore to diving to the water to catch a fish. Label each section. ALGEBRA 1 LESSON 5-1

7. Relating Graphs to Events Suppose you drink the remaining soda from a can in 10 seconds at a steady rate. Describe the graph of the change in height of the liquid over time. The graph would be a straight line from the original height at time 0 to zero height after 10 seconds. Time Height

8. Relating Graphs to Events ALGEBRA 1 LESSON 5-1 Use the graph for questions 1–4. 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. a jagged curve 4. Would a horizontal line, a straight slanted line, a curve, or a jagged curve best represent the calories you burn during the day? 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?
