As x increases, y decreases; r= -0.87
which graph best describes this?

Option A - Graph A

Step-by-step explanation:

Given : Scatter plot as x increases, y decreases; r= -0.87.

To find : Which graph best describes this?

Solution :    

The correlation r measures the strength of the linear relationship

between two quantitative variables.

r<0 indicate a negative association.    

If y decreases as x increases, there is a negative slope.

As Option A and D are negative slope.

In Option D The scatter plot is when r=-0.5 as points scatter a lot.

In Option A  the data points correlate relatively well. The closer the decimal is to 1 or -1, the better.

Therefore, Option A is correct.

As x increases, y decreases; r= -0.87 - The graph A.

a=r

d=q

c=p

b=s
