    should the equation not be y = 0.5x + 11.5? Is this a typo or an allowance for translating the line a third of the way to the middle point?

    Finding the equation of a regression line Steps to finding the line of best fit by eye. 1) Construct a scatterplot of the data. 2) Locate the point defined by the medians of the data sets. 3) Place a ruler on the scatterplot and adjust it until it runs through the centre of the data. 4) Draw in the line. 5) Calculate the gradient and the Y-intercept of the line. 6) Determine the equation using the general rule.
