Step-by-step explanation:

In order for a function to be linear, the power of the variable x must be 1.

Linear functions are a straight line. Non-linear have a curve and an exponent higher than 1.

Step-by-step explanation:

y = x/2 -19   That is linear

3y = x^2   That is parabolic  (not linear)

13y = 1/3x+5   That is linear

y = x +25/5   That is linear

y^3 =x      That is a cubic equation  (That is not linear)
