If the position vector of a point (–4, –3) be find

Given is the position vector of point (–4, –3).

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

Now, we need to find magnitude of i.e. .

Recall the magnitude of the vector is given as

Here, x = –4 and y = –3

Thus, .
