To measure displacement, we need to mark points using x- and y-axes. One difference between displacement and distance is that displacement can be negative, depending on the direction, just like co-ordinates of a point in a graph can be negative.
Recall that displacement is nothing but the change in position. $$\text{Displacement} =$$ $$\text{Final position}$$ $$- \text{Initial Position}$$

Look at the animation and choose the right option.
• The figure moves from $$x = 1$$ to $$x = 4$$. So, $$\mathrm{Displacement} \, = -3$$ along the +x direction.
• The figure moves from $$x = 1$$ to $$x = 4$$. So, $$\mathrm{Displacement} \, = 3$$ along the +x direction.
• The figure moves from $$y = 1$$ to $$y = 4$$. So, $$\mathrm{Displacement} \, = 3$$ along the +y direction.
• The figure moves from $$y = 1$$ to $$y = 4$$. So, $$\mathrm{Displacement} \, = -3$$along the +y direction.
