Answer:
This question seems to be incomplete, so i will answer it in a general way.
If we have a vector;
b = (b1, b2)
where b1 and b2 are the x-component and the y-component (respectively) of the vector b, then we can write the vector as:
b = (b1, b2) = b1*x^ + b2*y^
Where x^ = (1, 0) and y^ = (0, 1)
Are the unit vectors.
