Question

name kahlesa rosario 7th grade math date 9 - 3 - 2015 team says lesson 5: positive and negative integers exit ticket directions: complete each problem by showing all work. dont forget to use moli use the number line below to answer questions 1 - 3. 1: which of the following letter pairs are opposites? a. a and b b. a and c c. a and d d. b and c e. b and d f. c and d 2) nyle states that point a represent the opposite of - 5. do you agree or disagree with nyle? explain your reasoning. 3) circle the correct words to make the following statement true: point a is (the opposite / not the opposite) of point d because they are the (same distance / different distances) away from zero. 4) plot point m at the opposite of - 3 on the number line below. -5 -4 -3 -2 -1 0 1 2 3 4 5

Explanation:

Step1: Recall definition of opposites on number - line

Opposite numbers are the same distance from 0 on the number - line but on opposite sides.

Step2: Analyze distances of points from 0

Let's assume the intervals on the number - line are of unit length. If point B is at - 1, point A is at - 5, point C is at 1, and point D is at 5.

1. For question 1:

• Point A (-5) and point C (1) are not opposites. Point A (-5) and point D (5) are opposites as they are the same distance (5 units) from 0 on opposite sides. So the answer to question 1 is c.

1. For question 2:

• Point A is at - 5. The opposite of - 5 is 5. So Nyle is correct.

1. For question 3:

• Point A is at - 5 and point D is at 5. Point A is the opposite of Point D because they are the same distance away from zero.

1. For question 4:

• The opposite of - 3 is 3. So we plot Point M at 3 on the number - line.

Answer:

1. c. A and D
2. Agree. Point A is at - 5 and the opposite of - 5 is 5.
3. Point A is the opposite of Point D because they are the same distance away from zero.
4. Plot Point M at 3 on the number - line.
