Hello, I am trying to understand what approach to take to understand this linear regression. The equation shows: Y = 123 - 12.

Hello, I am trying to understand what approach to take to understand this linear regression. The equation shows: Y = 123 - 12.5X. The values for X that were used to develop the equation ranged from 2 to 10. If we assume you are now asked to estimate Y when X equals 30. Which of the following is most accurate?

A.) Y = -601.5

B.) = 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
