Which statement it true regarding their claims?
Adele is correct because only lines may have a negative slope.
Adele is correct because the y values increase as the x values decrease in graph A, so it shows a positive correlation.
Monte is correct because both graphs show a strong correlation.
Monte is correct because in both scatterplots, the y values decrease as the x values increase so both have a negative correlation.

Answer 1

Monte is correct because in both scatterplots the y-values tend to decrease as the x-values increase, which is the definition of a negative correlation.
