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.
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.
