A scatterplot is a visual representation of the relationship between two variables. It can detect a positive linear relationship, where an increase in x is associated with an increase in y, as well as a negative linear relationship, where an increase in x is associated with a decrease in y. It can also detect a relationship that is not linear, such as a curved or scattered pattern. Therefore, the answer is D - all of these.
