Graph? Which is linear

Below

Step-by-step explanation:

1. Linear because it is of the form y = mx + b. The variable x  is of the first degree.

The coefficient of x (1/3)  ( = slope) is positive so it is increasing.

2. This is non-linear because the variable x is an exponent.

3. Because  its of the second degree (x^2) - it is non-linear.

step-by-step explanation:

graph using a few selected

x         y

-1       15

0         6

1         2.4

2       0.96

i belive false if so your welcome if not well idk
