Question

The graph shows the distance in miles, d, a car travels in hours. ​ ​ Explain why the graph does or does not represent a proportional relationship between the variables d and t.

Answer 1

The graph represents a proportional relationship if it is a straight line passing through the origin.

Step-by-step explanation:

The graph represents a proportional relationship between the variables d and t if it is a straight line passing through the origin (0,0). This means that for every increase in time, there is a constant increase in distance. If the graph is not a straight line passing through the origin, it does not represent a proportional relationship.

Answer 2

The graph shows a proportional relationship because t=50, and that pattern follows.

Step-by-step explanation:

The graph shows a proportional relationship because t=50, and that pattern follows.
