In a study, fast-food menu items were analysed for their fat content (measured in grams) and calorie content. The goal is to predict the number of calories in a menu item from knowing its fat content. The least-squares regression line was computed and added to a scatterplot of the data:

The equation of the least-squares regression line is:
Calories = 204 + 11.4 × (Fat) The correlation between Calories and Fat is r = 0.979. Hence, r2 = 0.958. We might feel comfortable using the least-squares regression equation to predict calories for a menu item having fat content
