Final answer:
To find the values of m and n that satisfy the equation r = mp + np, we can set up a system of equations and solve for m and n.
Step-by-step explanation:
To find the values of m and n that satisfy the equation r = mp + np, where p = (2, -1), q = (1, 3), and r = (5, -6), we can set up a system of equations.
Using the values of r, p, and q, we can write:
(5, -6) = m(2, -1) + n(1, 3)
Expanding this equation gives us two equations:
5 = 2m + n
-6 = -m + 3n
Solving this system of equations, we can find the values of m and n.
