Additive and Multiplicative Relationships
Additive relationships mean you add the SAME number to any x-value to get the corresponding y-value. 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 x-value times the SAME number to get the corresponding y-value. 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).
