Comparing Additive and Multiplicative Relationships 8.1 Comparing Additive and Multiplicative Relationships How do you represent, describe, and compare additive and multiplicative relationships?

ADDITIONAL EXAMPLE 1 A Ben had 3 songs on his MP3 player. He is adding more songs. Show his progress in the table. • Complete the table. • List the ordered pairs from the table. (1, 4), (2, 5), (3, 6), (4, 7)

ADDITIONAL EXAMPLE 1 • Graph the ordered pairs on a coordinate plane.

ADDITIONAL EXAMPLE 1 B Glen is arranging tables and chairs for a party. He places 4 chairs at each table. • Complete the table. • List the ordered pairs from the table. (1, 4), (2, 8), (3, 12)

ADDITIONAL EXAMPLE 1 • Graph the ordered pairs on a coordinate plane.

8.1 LESSON QUIZ The table shows the cost of renting video games. 1. Is the relationship multiplicative or additive? Explain. Multiplicative; the cost is the number of video games times 3.

The table shows the cost of renting video games. 2. Graph the relationship of the number of games and their rental cost.

The table shows the cost of renting a bike at one bicycle shop. 3. Is the relationship multiplicative or additive? Explain. Additive; the cost is the number of hours plus $5.

The table shows the cost of renting a bike at one bicycle shop. 4. Graph the ordered pairs on a coordinate plane.

The graph shows one point on the graph of a multiplicative relationship showing late fees for overdue library books. Use the graph labels and what you have learned about multiplicative relationships to describe the situation that it represents. Then identify the rule and create a table of values for up to 5 days late. Graph the ordered pairs from the table.

The point (1, 5) is graphed. It shows that if a library book is 1 day late, the late fee is 5 cents. Rule: To find the late fee, multiply the number of days late by 5 cents.

Table 1:Multiplicatitive Complete each table. Show an additive relationship in the first table and a multiplicative relationship in the second table. Name a real world scenario that could be described by the example in each table. Table 1: Additive A 1 2 3 4 5 B   Table 1:Multiplicatitive A 1 2 3 4 5 B  

Find Someone Who… Write a real-world scenario using a additive or multiplicative relationship. When I say GO, you will find a partner and switch white boards. You are to solve your partners questions by making a table and plotting it on the graph.
