Answer: A

Explanation:

For there to be a negative association between x and y, the slope of the graph must be negative (so when x is increasing, y is decreasing).

  • From this, we can immediately eliminate sets B and D.

Now, we just need to determine which one has a linear relationship.

  • For set A, we see a constant decrease of 1 in the value of y for each time x increases by 1, so this is linear.
  • For set C, there is no consistent decrease in the value of y for each time x increases by 1, so this is not linear.
