  2. What will the population of Vermont be in 2010?

  3. What will the population of Vermont be in 2010? +58,446 +63,129 +53,308 +44,926

  4. What will the population of Vermont be in 2010? not linear! +58,446 +63,129 +53,308 +44,926

  5. What will the population of Vermont be in 2010? +58,446 +63,129 +53,308 +44,926

  6. What will the population of Vermont be in 2010? +58,446 +63,129 not linear... but close! +53,308 +44,926

  7. What will the population of Vermont be in 2010? +58,446 +63,129 +53,308 +44,926 We are going to use the average rate of change over the 40-years of data we have in order to estimate the population in 2010.

  8. What will the population of Vermont be in 2010? +40 +220,009

  9. What will the population of Vermont be in 2010?

  10. What will the population of Vermont be in 2010? Our prediction is that the population of Vermont will be 664,892 in 2010.

  11. The population of Vermont in 2006 was 623,908. Based upon this information, how accurate is the equation we have developed?

  12. The population of Vermont in 2006 was 623,908. Based upon this information, how accurate is the equation we have developed?

  13. The population of Vermont in 2006 was 623,908. Based upon this information, how accurate is the equation we have developed?

  14. The population of Vermont in 2006 was 623,908. Based upon this information, how accurate is the equation we have developed? Our equation overestimates the 2006 population by 18,983 people. Therefore, the 2010 value we previously found is likely high. Our slope of 5500 people/year tells us that our over-estimation puts us about three years worth above the actual.
