Answer:
both move at a constant speed.
Explanation:
As you can tell.....They are both straight lights both going t a certain point. They definently dont start the same journey on the same point so cross that one out. They dont move with variable speed so. And they dont have the same slope. If they had the same slope they would have the same direction all together. So they are going at a constant speed together because no matter where their point is, they are going to be going around the same rate.
