Answer:
The correct answer is option one and option four.
Step-by-step explanation:
y=3x and y=-ax are equal because they are opposites and can match to the other by the same numbers. I hope you know what I mean by that, I prob didn't say it right. But the other two opstions are not correct because they are different kind of equations, (additions, subtraction, multiplication, and division) I hope you understand. Good luck on future questions!!
