Additive and Multiplicative Relationships

The same value is added to each x-value to find the corresponding y-value

• Multiplicative 

• Additive Relationship

• 7

• No relationship

What is the correct equation for an additive relationship?

• y = x+a

• x = y+a

• y = ax

• a/x = m

What is the correct equation for a multiplicative relationship?

• y = x + a

• x = y + a 

• y = ax

• a/x = m

Each x-value is multiplied by the same factor  to find the corresponding y-value

• No relationship

• Additive Relationship

• Bad relationship

• Multiplicative Relationship

• Both data sets show additive relationships.

  In Data Set I, y is 5.5 more than x, and in Data Set II, y is 5 more than x.

• Data Set I shows a multiplicative relationship in which y is 5.5 times x.

  Data Set II shows an additive relationship in which y is 20 more than x.

• Both data sets show multiplicative relationships.

  In Data Set I, y is 5.5 times x, and in Data Set II, y is 5 times x.

• Data Set I shows an additive relationship in which y is 4.5 more than x.

  Data Set II shows a multiplicative relationship in which y is 5 times x.
