Drag each object to show whether distance is proportional to time in the situation represented.
A subway train that makes
4 stops in 12 minutes
An elevator that stops at each floor
for an equal amount of time
Line graph with straight line from origin upward. X-axis has 2 numbers: 2, 10. Label: Time (seconds). Y-axis labeled Distance (feet) with 2 numbers: 8, 40. Points plotted: (2, 8); (10, 40).
