To find the equation of the line of best fit for the data given in the table, you can use a spreadsheet to perform a linear regression. After performing this regression, you should obtain an equation of the form \(y = mx + b\), where \(m\) is the slope and \(b\) is the y-intercept.

Let's summarize the data points:

  • (1, 5)
  • (2, 9)
  • (3, 10)
  • (4, 10.5)
  • (5, 11)

Using a linear regression calculation, you could find that the line of best fit is approximately:

\[ y = 1.35x + 5.05 \]

Therefore, the correct answer is:

y = 1.35x + 5.05.
