Possible Answers:

Yes, 

No

Yes, 

Yes, 

Yes, 

Correct answer:

No

Explanation:

In order to determine whether or not the table shows a direct proportion, we will divide the quantities in the  coordinate column by the quantities in the  coordinate column. In order for the table to show direct proportion, each quotient should be the same value. 

In this example, each quotient isn't the same value; therefore, this table does not show direct proportion.
