Adele and Monte are discussing graphs with negative correlation. Adele claims that only graph B has a negative correlation. Mont
e claims that both scatterplots have a negative correlation.
Which statement it true regarding their claims?
A. Adele is correct because only lines may have a negative slope.
B. Adele is correct because the y values increase as the x values decrease in graph A, so it shows a positive correlation.
C. Monte is correct because both graphs show a strong correlation.
D. Monte is correct because in both scatterplots, the y values decrease as the x values increase so both have a negative correlation.

Step-by-step explanation:
Substituting y in the first equation
At x = 1.17
At x = -1.17
The intersection points are (1.17, 5.85k) and (-1.17, -5.85k)
The graph would intersect regardless of what value k is.
