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.

Answer:
(-3/2, 6)
Step-by-step explanation:
(-3,8) (6,-4)
As we move along the line segment with endpoints (-3,8) and (6,-4) from (-3,8) to (6,-4) x increases by 9 units (from -3 to 6) and y decreases by -12 units (from 8 to -4).
for ratio of 1:5
Since 1+5=6, the point we are looking for is 1/6 of the way from (-3,8) to (6,-4).
So, the desired point is
(-3 + (1/6)(9), 8 - (1/6)(12) )
= (-3 + 3/2 , 8 - 2)
= ( (-6 + 3)/2, 6)
= (-3/2, 6)
