A proportional equation follows the form y=kx, where k is the constant of proportionality.

Answer 1 is wrong because there is something added.

2 is correct as it follows this format.

3 is incorrect as it does not follow this format.

4 is correct as it follows the format (k is 1)

5 Is correct because it follows this format.
