Algebra Chapter Two Review

If the least squares regression line for a data set is y = -1 + 4x , what is the predicted value of y when x = 7?

• The predicted value of y when x = 7 is 27.

• The predicted value of y when x = 7 is 31.

• The predicted value of y when x = 7 is 15.

• The predicted value of y when x = 7 is 20.
