There's no proportional relationship between number of laps and minutes.
Step-by-step explanation:
The graph given above is a straight line graph, however, it does not cut across the point of origin (0, 0). As a result of this, it would be difficult to get a constant of proportionality, as you'd likely get different constant of proportionality between different points on the line. Thus, the ratio of y and x for each set of points may vary.
So therefore, the relationship between the x and y cannot be proportional.
We can conclude that the graph does not represent a proportional relationship between number of laps and minutes.
