Expert Answer:

Dear student
Displacement is denoted by a vector with its head at the final position & tail at the initial position. The direction of this vector is postive if it is directed along + axis, could be either +x- axis or + y axis.
The direction of this vector would be negative, if it directed along - axis, could be either - x axis or - y axis.
 
For example, for a ball thrown vertically up & caught at a point higher than initial position, will have its displacement vector diercted along + y axis. Displacement is positive.
For a ball thrown vertically up & caught at a point lower than initial position, will have its displacement vector diercted along - y axis . Displacement is negative.
 
We hope that clarifies your doubt.
