Lisa creates a scatter plot of the number of minutes she runs on the treadmill and the calories she burns. about how many more calories does she burn for every additional 5 minutes on the treadmill? a.10 b.25 c.50 d.100

The scatter plot shows the points and the line of best fit for the points. From the given points we can see that for every 5 minutes on the treadmill Lisa burns 50 calories on average.

We can confirm this by finding the slope of the best fit line. Two points on the line are: (5,50) and (10,100)

Slope of the line is:



Slope indicates how much calories are burned for every additional minute on the treadmill. So we can say, for every additional minute, Lisa burns 10 calories. So for every additional 5 minutes, Lisa will burn 50 calories. This can also be seen from the graph of the line.

Therefore the correct answer is option C

The expressions would be 0.25a
