 Proportional relationships Graph a proportional relationship The graph of a proportional relationship is a straight line through the origin. Graph the function y=2x You can graph a function by plotting ordered pairs. Find ordered pairs by plugging in values for x. Plug in x = 0. y = 2x y = 2(0) y = 0 The point (0, 0) is on the graph. Plug in x = 1. y = 2x y = 2(1) y = 2 The point (1, 2) is on the graph. Plot the points (0, 0) and (1, 2) on the graph. The graph of the equation y = 2x is the straight line connecting the points (0, 0) and (1,2)
