Given that the initial point of vector "u" is:
And the terminal point:
You need to find the Component Form of the vector with this formula:
In this case:
Then, you get:
Find the Magnitude using this formula:
In this case:
Therefore, by substituting values and evaluating, you get:
In order to find the direction of the vector "u", you need to use this formula:
Then, when you substitute the values of "x" and "y" into the formula and evaluate, you get:
Hence, the answer is:
