Question

60 POINTS AND BRAINLIE$T

Is this table linear? I need help!
Given from the table below, Is the table linear or nonlinear?

Answer 1

The table is linear because as x increases by 1, y changes by an average rate of |2|. You can also notice the tables both end in |+1|, which shows that the table has a constant rate of change between the two points at the end. Thus, the table is linear. If the table was nonlinear, there would be no constant rate of change between the 2 sets of data.
