Linear regression was found between two variables. The equation is: Y = 123 - 12.5X. Values for X that were used to develop the equation ranged from 2 to 10. Assume you are now asked to estimate Y when X equals 30. Which of the following is most accurate?
A. Y = -601.5
B. Y = 973.5
C. It would be inappropriate to estimate Y because due to the value of X
D. It would be inappropriate to estimate Y because the slope is negative
