a. there is a relationship between the variables that is not linear.
b. there is a linear relationship between the variables.
c. there is a linear relationship between the variables, and whenever the value of one variable increases, the value of the other variable increases.
d. there is a linear relationship between the variables, and whenever the value of one variable increases, the value of the other variable decreases.
