The following table displays the number of registered cars in America from 2008 to 2017 Year 2008 2009 2010 2011 2012 534,02 433,68 0 457,90 8 478,85 497,17 3 3 6 I Year 2013 2014 2015 2016 2017 707,26 572,07 5 603,44 631,16 680,12 8 5 2 4 1. Plot and label the above data on an A4 graph paper. Use x-axis to represent the years from year 2008 (x=0) onwards (every 2 cm represent 1 year). Use y-axis to represent the number of cars from 0 onwards (every 1 cm represents 50,000 cars). 2. Find the equation of "The line of Best Fit" in "slope intercept form". Round your figures to 1 decimal point. 3. What does the slope and y-intercept mean? 4. Use the equation found in step 2 to find the number of cars in 2020 & 2021. 5. Use the same equation to predict the number in 2030. 6. Use the internet to find the actual numbers of cars in America in years 2020 & 2021. Compare these actual numbers to the numbers found in step 4 above. If they are different, what are the reasons in your opinion? 7. Calculate the percentage errors in the number of cars in year 2020 & 2021
