Five-Minute Check (over Lesson 2–8) Main Idea and Vocabulary Example 1: Use Integers to Represent Data Example 2: Use Integers to Represent Data Example 3: Graph an Integer on a Number Line Example 4: Make a Line Plot • Use integers to represent real-world data. • negative numbers • positive numbers • opposites • integers • graph Use Integers to Represent Data GROWTH Write an integer that represents a height increase of 3 inches. An increase represents a positive number. Answer: The integer is +3 or 3. WEATHER Write an integer that represents a temperature of 12 degrees above zero. A. –12 B. 12 C. +12 D. both B and C 0% 0% A B 1. 2. 3. 4. 0% C A B C D 0% D Use Integers to Represent Data GOLF Write an integer that represents a golfer who is seven shots below par.

A. –8 B. 8 C. +8 D. both A and B 0% 0% A B 1. 2. 3. 4. 0% C A B C D 0% D Graph an Integer on a Number Line Graph –2 on a number line. Draw a number line. Then draw a dot at the location that represents –2. Answer: Graph –5 on a number line. A. B. C. D. 0% 0% A B 1. 2. 3. 4. 0% C A B C D 0% D Make a Line Plot WEATHER The table shows the lowest temperatures in some cities and towns. Make a line plot of the data. Draw a number line. –10 would be plotted farthest to the left and 15 farthest to the right. So you can use a scale of –10 to 15. Put an x above the number that represents each temperature in the table. Make a Line Plot Answer: VIDEO GAMES The table shows Carter’s score each time he played a video game. Make a line plot of the data. A. D. D A 0% A B C 0% 0% D C C. 1. 2. 3. 0% 4. B B.
