The final direction of travel is in the positive direction.
Work Step by Step
Velocity is a vector quantity, meaning that it measures not only magnitude, but also direction. On a graph, this is shown by the position of the plotted points: if its above the x-axis then it is going in the positive direction, and vice versa. At its final plotted point in this graph, the particle is above the x-axis, therefore its final direction of travel is positive.
