Use the following linear regression equation to answer the questions. X - 1.2 + 3.6x - 7.6xy + 2.5x4 (a) Which variable is the response variable? O KA O x2 Oxy Which variables are the explanatory variables? (Select all that apply.) (b) Which number is the constant term? List the coefficients with their corresponding explanatory variables. constant 12 X2 coefficient 3.6 Xy coefficient 7.6 X4 coefficient 2.5 (c) If x - 8, x - 6, and x4 - 4, what is the predicted value for x? (Use 1 decimal place.) 5.6 (d) Explain how each coefficient can be thought of as a "slope" under certain conditions. O If we look at all coefficients together, each one can be thought of as a "slope."
