Answer:
⟨-5, -1⟩
Step-by-step explanation:
Vector:
A vector is given by its endpoint subtracted by its initial point.
Vector u has initial point at (3, 9) and terminal point at (–7, 5)
Then

Vector v has initial point at (1, –4) and terminal point at (6, –1).
Then

What is u + v in component form?

⟨-5, -1⟩ is the answer.
