Final answer:
Without the actual graph or data points provided, we can't definitively say if the graph is proportional. Proportionality is characterized by a constant ratio and typically represented by a straight line graph that passes through the origin.
Step-by-step explanation:
To determine if the graph is proportional, we must look at the relationship between the variables represented on the graph. In a proportional graph, the ratio between the dependent and independent variables is constant, which means the graph will be a straight line passing through the origin. In the description provided, although there's no explicit graph to assess, a distance versus time graph typically shows the position (distance from a starting point) of an object over time.
If the position increases at a consistent rate over time, the object is said to have a constant velocity, and the graph would be a straight line. However, without seeing the actual graph or data points, we can't definitively answer if the graph is proportional. To check proportionality, we would calculate the slope (rate of change) at different intervals and see if it remains the same.
