Answer 3

You know its either A or C just from reading it.
When acceleration, it just means velocity is decreasing (slowing down.)

Answer 4

yeah i deduced that, however, I do not know which one is between those 2

Answer 5

Answer 6

When acceleration is negative, it means velocity is decreasing. (slowing down)
Sorry to forgot add negative earlier
Lets say a positive velocity is heading at a right direction.
A negative velocity would head at a left direction.

Answer 7

So we can slow down at any direction.

Answer 8

yes it was c !
