You know, the fastest and easiest way to solve this is to simply plug these values in to a Microsoft Excel spreadsheet, and then have it calculate the linear regression of the plotted points. Of course, you may calculate it manually yourself. If that's the case, I'd recommend getting familiar with the linear regression formula first. Good luck!
