The graph shows the distance a sloth travels in x minutes. Which statement about the sloth's speed in NOT true?

• The distance that the sloth has traveled is directly proportional to the time traveled.

• The sloth is traveling at a constant rate.

• The constant of proportionality for this relationship is 6ft/min

• The relationship between distance and time is not proportional because the distance traveled at zero minutes is zero feet.
