Based on the two given points, what is the relation between x and y?
'Show a point' to see another point with the same relation. Generate more points to help you make a guess.
If this one is too easy, enter any other coordinates for B and try again. This will create another relation for you to guess.
Try changing B to (7,14). What is the new relation?
How about (5,1)?
How about (5,13)?
Go on to change both A and B to explore other relations.
