For this case we have that the most appropriate trend line as you can see in the image is given by:
y = 5.098x + 9.118
The r value is given by:
r = 0.999
When r is very close to one, then the trend line has a good approximation.
Rewriting the equation we have:
y = 5.10x + 9.12
Answer:
The line of best fit given by a regression calculator for the data in the table is:
y = 5.10x + 9.12
