The graph of y = 2x+1 is a straight line. 1  When x increases, y increases twice as fast, hence 2x. 2  When x is 0, y is already 1.  So: y = 2x + 1.
The graph is a curve, not a This graph is also a curve. straight line. a nonlinear function. function. y = mx + b, where m represents the constant rate of change. Determine whether each equation represents a linear or nonlineardenominator. function. Explain.
