Exercise 9. Let u = (1,2) and v = (2, 1). Find a nonzero linear combination ī of u and v that's %3D perpendicular to u. Draw a picture to illustrate what the coefficients are measuring. (Hint: you may as well take the linear combination i to be of the form Au + v ; why is that? Then how would you find A?)

Exercise 8. Let u = (1, 2). Find a nonzero vector v e R² perpendicular to u. Show how to express
any vector (r, y) e R² as a linear combination of u and v. Illustrate by plotting u, v and (r, y) in the
plane and indicate what the coefficients are measuring. Use some specific examples and moderately
accurate pictures to verify.
