To solve the given problem, the question asks for the vector that has its coordinates at (2, 2) on the grid. The instruction states to provide the letter of the vector as the answer.

Let's break down the process:

1. Identify the point (2, 2) on the coordinate grid.
2. Check which vector originates from or passes through the point (2, 2).
3. Write down the letter corresponding to that vector.

From the image, the point (2, 2) appears to have the vector labeled "e" passing through it. Therefore, the answer should be e.

Would you like further details on this, or do you have any other questions?

Here are 5 related questions to expand your understanding:

1. What are the components of vector "e" in this graph?
2. How would you describe a vector's direction and magnitude?
3. What is the difference between position vectors and free vectors?
4. How can you find the angle between two vectors using their coordinates?
5. What is the relationship between vectors and matrices in transformations?

Tip: Remember that vectors can be represented by both their coordinates and their direction and magnitude!
