Answer:

1. not

2. not

3. not

4/5. linear

Step-by-step explanation:

Linear equations are equations where each term has an exponent of 1.

This means that they are x^1, not X^2 or X^3

you can tell if it is linear if you see no exponent.

1. x^3 not linear because it has an exponent of 3

2. X^2 not linear because it has an exponent of 2

3. (x-2)^2 not linear because it has an exponent of 2

4/5. 8(3+2x)-5 Linear because its exponent is 1.
