k, so I Ok, so I filled in the table easily t: -3, -2, -1, 0, 1, 2

                                                  x: -11 -8 -5 -2 1 4

                                                  y: 19 15 11 7 3 -1

But I don't know what the delta means! Any hints? Thanks!

Delta usually means   ' change in'

   as in change in x   per   change in  t       change in t   would be from -3 to 2    so delta t would be   5

                                               then do the same for the coresponding values you found for x

                                                        then just do the math    delta x  divided by delta t

Got it! So it would be 15/5, -20/5, -20/15?
