Answer:part a :yes it is a linear function because it is a straighten lined   Part b : LINEAR FUNCTION  Example: y = 2x + 1 is a linear equation: The graph of y = 2x+1 is a straight line. When x increases, y increases twice as fast, so we need 2x. When x is 0, y is already 1. NONLINEAR FUNCTION  An example of a nonlinear function is y = x^2. This is nonlinear because, although it is a polynomial, its highest exponent is 2, not 1.
