To determine which scatterplot represents a negative linear relationship, look for a plot where the points trend downward from left to right, indicating that as one variable increases, the other variable decreases.
If Scatterplot C displays this downward trend, then it is the correct answer. If another scatterplot (A, B, or D) shows this relationship instead, then that would be the correct choice.
Since I cannot see the image you're referring to, I suggest you identify the scatterplot that shows this downward trend. Choose that scatterplot as your response.
