Asked by alex
On a coordinate plane, the x-axis is labeled Minutes and the y-axis is labeled Distance (in blocks). Point A is (5, 8), point B is (10, 16), point C is (15, 24), point D is (24, 13).
Jose has been keeping a record of the distance he bikes and the time it takes him. He travels at the same unit rate each time and plots the distances for particular times.
Which point on the graph did Jose plot incorrectly if he is representing a proportional relationship?

Point D is incorrect.
A, B, and C all have the same unit rate: 8/5 = 16/10 = 24/15 = 1.6 blocks per minute, so they lie on the line y = 1.6x (a proportional relationship through the origin). D(24,13) gives 13/24 ≈ 0.54, which does not match 1.6 (if correct it would be 1.6·24 = 38.4).
