Possible Answers:

Correct answer:

Explanation:

In order to determine the constant of proportionality, 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, the constant of proportionality is

Example Question #149 : Ratios & Proportional Relationships

Identify the constant of proportionality (i.e. the unit rate) in the provided graph. 

2

Possible Answers:

Correct answer:

Explanation:

In order to determine the constant of proportionality, we need to divide the quantities from the  coordinate by the quantities from the  coordinate. In order for the graph to show a direct proportion, each quotient should equal the same value. 

First, we need to find a series of coordinate points:

2 1

Now that we have a series of coordinate points, we can divide to find the constant of proportionality:

All of the quotients are the same value; therefore, this graph does show direct proportion and the constant of proportionality is .

Example Question #150 : Ratios & Proportional Relationships

Identify the constant of proportionality (i.e. the unit rate) in the provided graph.
