Answer:
every time x goes up 1, y goes up 2
So the constant rate of change is 2
Step-by-step explanation:
let me know if I'm wrong
on the x side of the table it is adding 2 for every number.
On they y side of the tables it is adding 4 for every number.
It is asking for rate of change for each table not all together.
So I geuss x=2, y=4
