A) the stronger or more significant the relationship between the independent variable, X and the dependent variable, Y.
B) the weaker or less significant the relationship between the independent variable, X and the dependent variable, Y.
C) the more relevant the intercept is in the cost equation.
D) the less relevant the intercept is in the cost equation.
