Suppose for estimating y, the equation ŷ = 5 − 2x is obtained for the data, which of the following is true for this situation?
- A.
The y intercept of line is 2
- B.
The slope of line is negative
- C.
The line represents inverse relationship
- D.
None of the above

Show answer & explanation
Correct answer: B
The regression equation ŷ = 5 − 2x indicates a negative linear relationship. The slope of -2 means y decreases by 2 units for every one unit increase in x, while the intercept of 5 represents the predicted y value when x is zero.
