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
