The correct description of the pattern is:
"When the independent variable x increases by 1, the dependent variable y also increases by 1."
However, since this specific wording doesn't appear exactly in the provided responses, the option "None of these" would be the most appropriate choice.
In the given pairs: (-2,-1), (-1,0), (0,1), (1,2), (2,3), as x increases from -2 to 2, y increases from -1 to 3. The relationship shows that y increases by 1 for every increase of 1 in x.
