x y
−12 −8
−8 −6
−4 −4
0 −2


Mina said that the function is linear.

Mina, because for every 2-unit increase in x, there is an increase in y by 4
Mina, because for every 4-unit increase in x, there is an increase in y by 2
Jenna, because the point (0, −2) does not lie on the straight line that contains the other points
Jenna, because the point (−12, −8) does not lie on the straight line that contains the other points
