In linear spatial filtering, what is the pixel of the image under mask

1.	In linear spatial filtering, what is the pixel of the image under mask corresponding to the mask coefficient w (1, -1), assuming a 3*3 mask?(a) f (x, -y)(b) f (x + 1, y)(c) f (x, y – 1)(d) f (x + 1, y – 1)The question was asked in final exam.This interesting question is from Spatial Filtering in section Intensity Transformations and Spatial Filtering of Digital Image Processing
Answer» CORRECT CHOICE is (d) f (X + 1, y – 1) The best explanation: The pixel corresponding to mask coefficient (a 3*3 mask) w (0, 0) is f (x, y), and so for w (1, -1) is f (x + 1, y – 1).
