Which of the following situations represent linear growth? Check all of the boxes that apply

I can't see the answer choices, so I'll do my best to explain.

Step-by-step explanation:

Linear growth is growth where the growth is the same in each step. This means the line is straight, or linear. An example would be y = x or y = 6x + 1. As long as there is no exponent on the variable or it is not in the bottom of a fraction, it should be linear.
