Answer :

Given A = (–1, 3) and B = (–2, 1)


We know position vector of a point (x, y) is given by, where and are unit vectors in X and Y directions.


Let position vectors of points A and B be and respectively.



We also have.


Recall the vector is given by







Now, it is given that there exists a point say (x, y) whose position vector is same as.


We know position vector of a point (x, y) is given by.




By comparing both the sides, we get x = –1 and y = –2


Thus, (–1, –2) is the tip of position vector that is same as .
