(please help.. it's urgent. thanks <3)

Answer 1

The higher value of X is associated with a lower value of Y so this is a negative association. It is also a nonlinear association because the ratio of change is not constant. For example X changes from 1 to 2, Y changes from 120 to 115 opposed to X changes from 5 to 6 while Y changes from 89 to 40.
