A Because the x-values increase by 1 as the y-values decrease by 2.
B Because the x-values and y- values need to be increased by the same number.
C Because there is no single pattern between changes in y-values.
D Because the x-values increase by 2 as the y-values decrease by 1.
E Because there is no single pattern between changes in x-values.

A) Yes, it represents a linear function.
B) Justification: A) Because the x-values increase by 2 as the y-values decrease by 1.
This shows a constant rate of change (the slope) between the x-values and y-values, which is characteristic of a linear function.
