The pair of variables that would be expected to be represented by a scatterplot with a negative correlation is:
the number of concert tickets purchased and the number of concert tickets still available for purchase.
As the number of concert tickets purchased increases, the number of concert tickets still available for purchase decreases, which indicates a negative correlation. In contrast, the other pairs either do not show a clear negative correlation or do not relate to each other in a way that would suggest a negative correlation.
