This is a problem that would take a very long time to do by hand. So a calculator is recommended. If you have a TI calculator (such as the TI 83) then use that. The calculator I'm going to use is GeoGebra. I've attached the results in the image attachment.
The line of best fit (aka the regression line) that GeoGebra produces is the equation y = 1.862 - 0.138
Which means the answer is choice A
