How Fast Does © 2001, 2003 Rev. 07.15.03 Your Race Car Go? 2 Fast Freddy’s Answer Sheet 1. Think of the data above as a set of ordered pairs where the year stands for the x-coordinate and the speed stands for the y-coordinate. The first ordered pair is (1912, 78.72). Graph all of the ordered pairs on a grid. 2. All of the points on your graph do not lie on the same line. However, draw a single straight line that you think “best” represents the data. This line is called the “line of best fit.” The number of points above your line of best fit should be about the same as the number of points below the line. 3. From your line of best fit, predict the average winning speed for 1977. This process is called “interpolation.” 4. Extend your line of best fit to predict the average winning speed for 1995. This process is called “extrapolation.” 5. Find ordered pairs assigned to two points on your line of best fit. Use these two ordered pairs to find the equation of your line of best fit in slope-intercept form. 6. You can use the equation you obtained in Exercise 5 to predict average winning speeds in the future. Use your equation to predict the average winning speed in the year 2002.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
