Answer 3

your choice in incorrect because they do not represnt or reflect a constant change

proof:
(0,0)(1,2)
slope = 2

(2,8)(3,18)
Slope = 10

slopes are different thus the change is not constant thus nonlinear

let's try the 1st set of data
(0,3)(1,5)
slope = 2

(2,7)(3,9)
Slope = 2

slopes are identical thus change is constant thus linear
sorry for keep saying thus but because there are too many needs for a thus lol
