1 Pre-Algebra Interpreting Graphs and Tables 1-9

2 Use the table to answer the following: 1. In which week did Alicia earn the most? 2. What is the average amount Alicia earned in one week? week 3 $5 Week Savings 1$3 2$5 3$10 4$2 5$6 6 $4 Warm Up

3 Learn to interpret information given in a graph or a table and make a graph to help solve problems.

4 Home Cleaners Mall Market 75 at 1:15 72 at 1:45 80 at 4: at 1:05 95 at 1: at 3: at 4:20 Location Temperature on Arrival Temperature on Departure The table below show how quickly the temperature can increase in a car that is left parked during an afternoon of errands when the outside temperature is 93F.

5 The table gives the speeds in mi/h of three cars at given times. Tell which car corresponds to the situation. Car 1 Car 2 Car 3 Time 1:00 1:051:10 1:151: Matching Situations to Tables

6 A. Mr. Lee is traveling on the highway, and he pulls over to make a call on his cell phone. Then he gets back onto the highway. Car 3 - Mr. Lee starts to slow down after 1:00. After making his phone call, he gets back onto the highway and resumes his speed of 55 mi/h. Car 1 Car 2 Car 3 Time 1:00 1:051:10 1:151: Matching Situations to Tables

7 B. Mrs. Healy is driving on the freeway between 1:00 and 1:20 and encounters no traffic. Car 2 - Mrs. Healy car maintains a speed between 50 mi/h and 55 mi/h. Car 1 Car 2 Car 3 Time 1:00 1:051:10 1:151: Matching Situations to Tables

8 C. At 1:00 Mr. Johns estimates that he will arrive at his destination in approximately 20 minutes. Car 1 - Mr. Johns speed begins to decrease to 0 sometime between 1:15 and 1:20. Car 1 Car 2 Car 3 Time 1:00 1:051:10 1:151: Matching Situations to Tables

9 The table gives the speed in mi/h of three runners at the given times. Tell which runner corresponds to the situation. Time 8:00 8:10 8:20 8:30 8:40 Runner Runner Runner A. Jamie begins the race, and soon feels a pain in a muscle. He is unable to complete the race. Runner 2Jamie begins at a fast speed. His speed decreases as he feels a pain in a muscle, and then decreases to 0 when he stops. Example

10 The table gives the speed in mi/h of three runners at the given times. Tell which runner corresponds to the situation. Time 8:00 8:10 8:20 8:30 8:40 Runner Runner Runner B. Melissa builds up her speed during the beginning of the race. She maintains her running speed for the remainder of the race. Runner 1Melissa begins running at a rate of 6 mi/h and then speeds up to 7 mi/h. She maintains 7 mi/h for the remainder of the race. Example

11 The table gives the speed in mi/h of three runners at the given times. Tell which runner corresponds to the situation. Time 8:00 8:10 8:20 8:30 8:40 Runner Runner Runner C. Ann decides to alternate between running and walking during the race. Runner 3Ann is running at a rate of 8 mi/h and then walks at a rate of 3 mi/h. She continues alternating between running and walking. Example

12 Tell which car in Example 1 corresponds to each graph. Car 1 Time Speed View Table Matching Situations to Graphs

13 Tell which car in Example 1 corresponds to each graph. Car 2 Time Speed View Table Matching Situations to Graphs

14 Tell which graph corresponds to the situation described in Example 1. Car 3 Time Speed View Table Matching Situations to Graphs

15 The table gives the speed in mi/h of three cars at the given times. Tell which car corresponds to the situation. Car 1 Car 2 Car 3 Time 1:00 1:051:10 1:151: Return

16 Tell which graph corresponds to the situation described in Example 1: Try This 1. A. Jamie begins the race, and soon feels a pain in a muscle. He is unable to complete the race. Graph 2Jamie is unable to complete the race, so his speed decreases to zero. Example

17 Tell which graph corresponds to the situation described in Example 1: Try This 1. B. Melissa builds up her speed during the beginning of the race. She maintains her running speed for the remainder of the race. Graph 1Melissas speed increases at the beginning and then the graph remains constant. Example

18 Tell which graph corresponds to the situation described in Example 1: Try This 1. C. Ann decides to alternate between running and walking during the race. Graph 3Anns speed decreases and increases at steady intervals throughout the race. Example

19 Create a graph that illustrates the temperature (F) inside the car. Work Cleaners Market 65 at 4:50 65 at 5:10 42 at 4:30 49 at 5:40 Location Temperature on Arrival Temperature on Departure 68 at 12:30 60 at 5:00. Car Temperatures Creating a Graph of a Situation

20 Create a graph that illustrates the information in the table about the distance traveled during a family vacation. Time 8:00 10:00 12:00 2:00 Distance (mi) Time Distance (mi) Distance TraveledExample

21 Tell which table corresponds to the situation. A tour bus sits at the gas station while the mechanic inspects the tires. It then leaves and make its first stop five miles down the road. The bus then continues on to its destination by getting on the expressway and driving 40 miles. Table 1 TimeSpeed 3:0020 mi/h 3:0520 mi/h 3:10 0 mi/h 3:1555 mi/h Table 2 TimeSpeed 3:00 0 mi/h 3:0520 mi/h 3:10 0 mi/h 3:1555 mi/h Table 3 TimeSpeed 3:000 mi/h 3:0510 mi/h 3:1020 mi/h 3:1555 mi/h Table 2 Lesson Quiz
