A negative relationship between two variables means that as one variable increases, the other variable decreases. This relationship remains the same regardless of which variable is on the vertical or horizontal axis. Therefore, if the price of jelly was placed on the vertical axis and the price of peanut butter was placed on the horizontal axis, the relationship would still be negative and inverse. Choice D is the best choice as it correctly identifies the relationship as negative and inverse.
