1)Given the linear model 3y = 6x + 14 , find the residual when x=9 and the actually data point is found to be (9, 54). Round to the nearest hundredth.

2)Given the linear model 8x + 6y = 7, the "Fit" when x=-5 would be...? Round to the nearest hundredth.

3) Given the linear model -5x - 4y + 9 = 0, find the residual when x=-7 and the actually data point is found to be (-7, 2). Round to the nearest hundredth.

4) The following linear model is created: y = 8x+7. What is the predicted value of the dependent variable when the independent variable has a value of -0.3?
