    Linear Regression Equation

    I have a question that I'm stuck on and was wondering if someone could help out:

    For a simple linear regression equation to be a perfect estimator of the dependent variable, which of the following has/have to be true?

    a. The standard error of the estimate is zero
    b. All the data points are on the regression line
    c. The coefficient of determination is -1
    d. a and b but not c
    e. a and b and c

    d. a and b but not c
    e. a and b and c
    d - since a perfect estimator will have R^2=1
