After spending some time guessing what is written in your post, I know the answer.


Yes, the data is linear.


For each increase of x by 4 units the variable y response decreases by 5 units:


y%5Bi%5D = -2 - %285%2F4%29%2A%28x%5Bi%5D-%28-9%29%29%29,  i = 1, 2, 3, 4.

----------------

Let me show you how to formulate it in a right way: 
     Whether the relationship shown in the table is linear ?


        x  -9  -5  -1   3

        y  -2  -7  -12  -17

=============

Notice that using the "space" between the numbers is necessary to show a sequence in a right way.

Using the space in combination with the comma is even better.
