If all linear relationships can be shown as tables, does that mean all tables are linear? Look at the six tables shown below.

1 Extend as many of the tables as you can by adding the next (x,y) pair in the sequence.

2 If the table is linear, write down your prediction of what the y-value will be when x = 0.

3 If the table is not linear, write not linear instead of the y-intercept.
