Additive and Multiplicative Relationships
Additive relationships mean you add the SAME number to any xvalue to get the corresponding yvalue. If it's not the same number every time, it is NOT an additive relationship. Subtraction can be an additive relationship because subtracting a number is the same as adding a negative number (example: 5  2 = 5 + (2)).
Multiplicative relationships mean you multiply any xvalue times the SAME number to get the corresponding yvalue. If it's not the same number every time, it is NOT multiplicative. Division can be a multiplicative relationship because dividing by a number is the same as multiplying by its reciprocal (flip the number). Example: 12 ÷ 4 = 12(1/4).
