Find the equation of the regression line for the given data. Then construct a scatter plot of the data and draw the regression line. (Each pair of variables has a significant correlation.) Then use the regression equation to predict the value of y for each of the given xvalues, if meaningful. The caloric content and the sodium content (in milligrams) for 6 beef hot dogs are shown in the table below.

a)
predicted val=41.505+180*2.573=  504.645 
b)
predicted val=41.505+100*2.573=  298.805
