The tables show the relationships between x and y for two data sets.

Which statements describe the relationships between x and y in Data Set I and Data Set II?

• 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.

Which situation can be represented by the equation?

 $y=12x$  

• Victoria went to school for x years.
