You can
put this solution on YOUR website!Non-linear.
See how the x values are increasing by one.
If the pattern were linear the y values would
be increasing or decreasing by some constant
number. But they are not; they first decrease
by 5, then 3, then 1, then increase by 1, then 3
The change is not consistent so the pattern is
not linear.
