A line of best fit can be roughly determined using an eyeball method by drawing a straight line on a scatter plot so that the number of points above the line and below the line is about equal (and the line passes through as many points as possible). A more accurate way of finding the line of best fit is the least square method .

The closer to 1, the better the fit. Its sign will also tell you whether it is a positive or negative correlation. So 0.9702 is a really strong positive correlation! m = 70.5769 is the slope of the best fit line; b = 868.077 is the y-intercept of the best fit line (see it on the graph?) So the equation of the best fit line (purple) is y=70.58x ...
