Unfortunately, Google Sheets wouldn't allow me to do a linear regression on sleep and studying, so I moved everything over onto Microsoft Excel. I extracted only the relevant data before plotting. Below, I was able to show linear regressions on the two pieces of data that I wanted. It makes the increase in studying and no change in sleep much more blatant.

I also minimized the range of the max and min values on the x- and y-axis so that the changes would seem much bigger.
