Question 56·Medium·Two-Variable Data: Models and Scatterplots

A scatterplot shows the relationship between the distance a cyclist rides in a week and the total calories the cyclist burns that week. Let $x$ be the number of 5-kilometer segments the cyclist rides in a week, and let $y$ be the total calories burned that week. A line of best fit for the data is given by

According to the line of best fit, approximately how many calories are predicted to be burned for each additional kilometer the cyclist rides in a week?
