Example Questions

Example Question #23 : Decide If Two Quantiies Are In A Proportional Relationship: Ccss.Math.Content.7.Rp.A.2a

Does the table provided show a direct proportional relationship? If so, then identify the proportion.

Screen shot 2016 02 17 at 9.45.24 am

Possible Answers:

Yes,

Correct answer:

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.
