Write a function that matches the description. a cosine function has a maximum of 5 and a minimum value of -5. f (r) =

Solve by any method (graphing, substitution or linear combination)y = x - 82x + 3y = 1a) (2, -6)b) (5, -3)c) (4, -4)d) (0, -8)i figured it out. the answer is (5, -3)

3x + 4y = 5 x- 3y = -7 solve by substitution
