Chapter 4.3, Problem 39SE

For the following exercises, consider this scenario: The profit of a company increased steadily over a ten-year span. Thefollowing ordered pairs show the number of units sold in hundreds and the profit in thousands of over the ten-yearspan, (number of units sold, profit) for specific recorded years:

$\left(\text{46},\text{ 25}0\right),\left(\text{48},\text{ 3}0\text{5}\right),\left(\text{5}0,\text{ 35}0\right),\left(\text{52},\text{ 39}0\right),\left(\text{54},\text{ 41}0\right).$

Use linear regression to determine a function y,where the profit in thousands of dollars depends onthe number of units sold in hundreds.
