How do you identify if the following as linear or nonlinear y=5x-4? Algebra Quadratic Equations and Functions Linear, Exponential, and Quadratic Models 1 Answer VinÃcius Ferraz Jul 6, 2017 It's not linear. Explanation: If #f# were linear then #f(lambda a) = lambda f(a) and f(a + b) = f(a) + f(b)# but #f(x) = 5x - 4 => f(lambda x) = 5 lambda x - 4# #ne lambda f(x) = 5 lambda x - 4 lambda# also #f(a + b) = 5(a + b) -4 ne f(a) + f(b) = 5a - 4 + 5b - 4# Answer link Related questions What is the linear regression line?
