Graph A shows a consistent relationship between time and distance. We know this fact because as seen in graph A the line is straight and progresses without any changes. The slope and line is consistent, meaning that the relationship between time and distance is also consistent. Some differences between graph a and b is that graph b does no carry on in a straight line, it goes up and down and isn’t consistent. One difference is that graph a has a direct positive relationship, meaning that as the x variable increases, so does the y variable. This isn’t true for graph b though.
