Question

Find the constant rate of change.

  1. 3
  2. -3
  3. 20
  4. Not a constant slope/Non-Linear

The correct answer is: -3


    The constant rate of change is -3.
    we can see that :-
    0->20 , 1->17 , 2->14 , 3->11 .........so on
    as we increase input by 1 the output is getting decreased by -3
    so, the constant rate of change is -3
