The two points on the graph are given by the linear function f. a. Use the two points to find the equation that represents the l
inear function f. b. What is f(6)? -1 1 2 3 4 5 -1 1 2 3 x y x y graph a. The equation nothing represents the linear function f. (Simplify your answer. Type an equation using x and y as the variables. Use integers or fractions for any numbers in the equation.)
