Is the relationship linear? Why or why not?

Answer 1

did you notice:

12-9=3
15-12=3

so what is your verdict ?

Answer 2

linear means that the change in y is a constant multiple of the change in x. So, going from point to point, make a table of the changes.

x-change y-change
1 3
1 3

so, the change in y is always 3 times the change in x. So, yes, the relationship is linear:

y = 3x+6

Answer 3

Thank you so much ^^
