Help please,, will mark brainlest 1) Which variable did you plot on the x-axis, and which variable did you plot on the y-axis?
Explain why you assigned the variables in that way.

2) Write the equation of the line of best fit using the slope-intercept formula y = mx + b.
Show all your work, including the points used to determine the slope and how the
equation was determined.

3) What does the slope of the line represent within the context of your graph? What does the y-intercept represent?

4) Test the residuals of two other points to determine how well the line of best fit models the data

5) Use the line of best fit to help you to describe the data correlation
How many calories do we expect from EACH gram of fat, based on your line of best fit?

6) Using the line of best fit that you found in question 2, approximate the total calories
based upon 22 grams of fat

7) According to your line of best fit, how many grams of fat would be in a 1,000 calorie
sandwich?
