Given the information, what is the slope 

r = 0.979 (correlation between x and y)
x = 40.35 grams (mean of the values of x )
y3 662.88 calories (mean of the values of y)
Sx = 27.99 grams (standard deviation of the values of x)
s, = 324.90 calories (standard deviation of the values of y)
Sy
The slope of the least-squares regression line is:

In many fast food restaurants, there is a strong correlation between a menu item's fat content (measured in grams) a
its calorie content. We want to investigate this relationship. Using all of the food menu items at a well-known fast fo
restaurant, the fat content and calorie content were measured. We decide to fit the least-squares regression line to the
data, with fat content (x) as the explanatory variable and calorie content (y) as the response variable. A scatterplot of
the data (with regression line included) and a summary of the data are provided. Ond of the menu items is a hamburge
with 107 grams of fat and 1410 calories.
