Your neighbor burns 100 Calories in 10 minutes​ cross-country skiing. There is a proportional relationship between Calories burned and time. Find the unit rate. Then use the unit rate to graph this relationship.

Answer 1

To find the unit rate, we divide the amount of Calories burned by the time it takes to burn those Calories.

Unit Rate = Calories burned / Time

In this case, the unit rate is:
Unit Rate = 100 Calories / 10 minutes
Unit Rate = 10 Calories/minute

To graph this relationship, we can take the time on the x-axis and the calories burned on the y-axis. For every 1 minute on the x-axis, we can plot 10 calories on the y-axis.

The graph will start at (0, 0) and we can plot other points by moving 1 minute to the right and 10 calories up on the graph.

The line representing this relationship will have a slope of 10 (rise of 10, run of 1) and pass through the origin (0, 0). The graph will be a straight line with a positive slope.
