A data set contains an independent and dependent variable. Which must be true of the data set if a linear function can be used to represent the data? The set must have a constant additive rate of change. The set must have a constant multiplicative rate of change. The values in the set must be positive. The values in the set must be increasing.

When we have dependent and independent variables we will have a linear relationship.
Let x be the independent variable and y be the dependent variable.
To write the relationship we will have :
y = kx + c
Where k and c are constants.
In the case of a line the constant k is the gradient.
A multiplicative change is a log form and it is given by :
Y = Ck^x
The relationship is not linear but exponential.
The correct answer is thus :
Additive rate of change.
