Final answer:
The vector can be expressed as (0,2) in component form.
Step-by-step explanation:
To express the vector with initial point P(-1,-1) and terminal point Q(-1,1) in component form, we need to find the difference between the x-coordinates and the y-coordinates of the two points.
The x-coordinate difference is: -1 - (-1) = 0
The y-coordinate difference is: 1 - (-1) = 2
Therefore, the vector can be expressed as ( 0, 2) in component form.
