Question 1

1.

Still Running--Mr. Hernandez loves to run, and his running pace is shown below.

Graph the coordinate pairs. Is this a proportional relationship? Use evidence from the table AND the graph.

#2: Explains using appropriate evidence from tables and graphs

Question 2

2.

Air Alexanders™--Alex saw how much money Mr. Mancini was making from his Air Mancinis™ so he wanted to start his own line of basketball shoes. The prices for pairs of Air Alexanders™ are shown in the table:

Is this a proportional relationship? Explain using evidence from the tables AND graph.

Question 3

3.

Takis are Back!--Back at Ms. P's Place, Takis are sold for the following prices:

Graph the coordinate pairs.
Is this a proportional relationship? Use evidence from the graph.

#1: Accurately computes unit rates
#2: Explains using appropriate evidence from the graph

Question 4

4.

Life Savings--Andrea is plotting how much money she has in her bank account over time. She starts with $30 and every week she saves $5 more.

Is the following statement true or false?

"Using only the graph, Student McStudentson can tell that this is a proportional relationship because it is a straight line."

This is TRUE because a straight line always shows proportionality.

This is FALSE because the graph needs to be both a straight line and going through the origin. This graph does not go through the origin, so it is not proportional. 

This is TRUE because she is adding a constant $5 every week.

This is FALSE because the graph is blue.

Question 5

5.

BE CREATIVE--Create your own table and graph that shows a relationship that is NOT proportional.

Make sure to...
1) Write out a word problem
2) Complete the table
3) Complete the graph and explain why it is not proportional.

Question 6

6.

Berry Picking—The following table gives the number of people picking strawberries in a field and the corresponding number of hours worked by each person.

Graph the coordinate pairs from table. Is this a proportional relationship? Please use evidence from the graph AND the table.

CFS
#1: Accurately computes unit rates
#2: Explains using appropriate evidence from tables and graphs

Awesome work! You can either...

1) Continue the IXL diagnostic
2) Work on the recommended graphing skill (Search Code: AAN)
