Sophia, Evelyn, and Maya took a taxi ride in New York City. They noticed a pattern between the distance the taxi traveled and the cost of their ride. Is this relationship proportional? Explain.

• The relationship is not proportional because the cost does not start at zero when the distance is zero.

• The relationship is proportional because the cost of the ride increases in a straight line as the distance increases.

• The relationship is not proportional because the cost of the ride does not increase in a straight line as the distance increases.

• The relationship is proportional because the cost increases as the distance increases.
