Use linear regression to find the equation for the line that best fits the data. Round both numbers to two decimal places. Write your final answer in the form of an equation [tex]$y = mx + b$[/tex].

Answer :

To determine the equation of the line that best fits the given data using linear regression, we need to find the slope ([tex]\(m\)[/tex]) and the y-intercept ([tex]\(b\)[/tex]) of the line.

Given the following data points:

[tex]\[ \begin{array}{|c|c|c|c|c|c|c|} \hline x & 1 & 2 & 3 & 4 & 5 & 6 \\ \hline y & 87 & 106 & 125 & 155 & 164 & 180 \\ \hline \end{array} \][/tex]

The slope ([tex]\(m\)[/tex]) and the y-intercept ([tex]\(b\)[/tex]) for the best-fitting line have been calculated, and they are:

- Slope: [tex]\(m = 19.11\)[/tex]
- Y-intercept: [tex]\(b = 69.27\)[/tex]

Thus, the equation of the line that best fits the data is:

[tex]\[ y = 19.11x + 69.27 \][/tex]

This equation represents the relationship between [tex]\(x\)[/tex] and [tex]\(y\)[/tex] based on the given data points, where [tex]\(x\)[/tex] is the independent variable and [tex]\(y\)[/tex] is the dependent variable.
