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

• Both data sets show additive relationships.  In Data Set I, y is 5 more than x, and in Data Set II, y is 6 more than x.

• Both data sets show multiplicative relationships.  In Data Set I, y is 3 times x, and in Data Set II, y is 5 times x.

• Data Set I shows an additive relationship in which y is 5 more than x.  Data Set II shows a multiplicative relationship in which y is 5 times x.

• Data Set I shows a multiplicative relationship in which y is 6 times x.  Data Set II shows an additive relationship in which y is 4 more than x.
