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 yvalue will be when x = 0.
3 If the table is not linear, write not linear instead of the yintercept.
A

B


when x=0, y will equal 
when x=0, y will equal 

C

D


when x=0, y will equal 
when x=0, y will equal 

E

F


when x=0, y will equal 
when x=0, y will equal 
What do you Notice?  What do you Wonder?
