The graph shows the number of jam jars filled by two different machines over several minutes. a graph measuring number of jars and time. two lines, labeled machine a and machine b, exit the origin to show that distance increases as time increases the equation y = 3x represents the number of jars, y, machine a fills in x min. which equation could represent the number of jars filled by machine b? y = 1.5x y = 3x y = 6x y = 8x
