If an object travels with positive velocity in the x-direction, can it have a negative acceleration along the x-axis at the same time?

Question

(I think it can't both should be positive- because when you draw the velocity time graph - the gradient (acc.) is also positive) ???? =/

Answer 1

Positive velocity, negative acceleration. Happens every time I approach a red light on the highway, slowing down (deaccelerating)>
