Chapter 4.3, Problem 41SE

For the following exercises, consider this scenario: The profit of a company decreased steadily overa ten-year span.The following ordered pairs show dollars and the number of units sold in hundreds and the profit in thousands ofover the ten-year span (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.
