Answer
A
There is a strong negative relationship.
B
There is a strong positive relationship.
C
There is a weak positive relationship.
D
There is little to no linear relationship.

Explanation

As Maria spends more on dining out, the amount she saves generally decreases: for example, she saves $150 when spending $20, but $80 when spending $75. The values follow a fairly consistent downward trend, so they show a strong negative relationship. The correct choice is A, “There is a strong negative relationship.”
