Question

The points on the graph demonstrate the proportional relationship of the distance that was traveled over time by a tortoise.



Which statement is true?

Responses
A The point (10, 12) means that a distance of 10 miles was traveled in 12 hours.The point (10, 12) means that a distance of 10 miles was traveled in 12 hours.
B The point (15, 18) means that a distance of 18 miles was traveled in 15 hours.The point (15, 18) means that a distance of 18 miles was traveled in 15 hours.
C The point (5, 6) means that the slope of the line is

. The point (5, 6) means that the slope of the line is 5/6 .
D If the line was extended, it would pass through the point (25, 36).

Answer 1

B

The points are (time, distance). So (15, 18) means 18 miles were traveled in 15 hours (and the constant rate is 18/15 = 6/5 miles per hour).
