If you consider forward as the positive direction, as many people probably would... then what sign would the backwards direction be?

If this just confused you, I'm sorry! I want to make a small point, though, that signs often matter in physics.

negative

Right! So if the velocity is backwards, it is considered negative. So if you see that the velocity is negative, the velocity is backwards :)

Oh, I guess I should also say... If the velocity is backwards, then you'll see that the velocity is negative!

if the velocity line or curve is below velocity = 0, which will be below the time axis because the time axis is at velocity = 0, then the velocity is backwards.

From t=0, meaning "the start", this guy was heading backwards. At various speeds! But backwards the whole time. At the end, there, he or she was heading backwards pretty fast (compared to how fast she or he was going earlier).
