Which of the following is a true statement?

Option: D is the correct answer.

The k-value is:

The table of values of x and y are given as follows:

    x        y

   -4        1

    8       -2

    12      -3

    20      -5

We know that x and y are said to be in proportional with constant of proportionality k if there is a constant k such that:

for different ordered pair (x,y)

Here for ordered pair (-4,1) we have:

Similarly for all the  other ordered pair we get:

k is a constant and

    Hence, the answer is:

          Option: D

wait this depends wether emily and zach how they are thinking.

yes they are the same.
