8 40
12 59

Answer 1

Therefore, the equation of the line of best fit for the given data, rounded to the nearest tenth, is y = 4.8x + 5.4.

Step-by-step explanation:

To find the equation of the line of best fit for the given data, we can use the linear regression feature on a graphing calculator. There are many online calculators available that can help us with this task. Here is one such calculator.

To use this calculator, we need to enter the data points in the table provided. The first column should contain the x-values, and the second column should contain the y-values. Once we have entered the data, we can click on the “Calculate now” button to get the results.

Using the calculator, we get the following equation of the line of best fit for the given data:

y = 4.8x + 5.4

Rounding each value to the nearest tenth, we get:

y = 4.8x + 5.4

Therefore, the equation of the line of best fit for the given data, rounded to the nearest tenth, is y = 4.8x + 5.4.
