I have the equation (y = mx + c) for this line.

How to draw a best fit line by hand. Users have manually drawn a straight line of best fit through a set of data points. Examine the data and determine the visual trend of data. In this lab you will need to determine whether or not a graph expresses a linear relationship.

Generate lines of best fit and basic regression analysis for free online with excel, csv, or sql data. This worksheet gives your students detailed information on how to draw lines of best fit followed by multiple opportunities to put this into practice. In the previous worked example and exercises, you drew the line of best fit by hand.

Try to have the line as close as possible to all points, and a similar number of points above and below the line. Are there any anomalous results? Is there any obvious correlation in the data?

Start by looking at the data points and asking yourself the following questions: How can you draw a line of best fit for a graph you draw by hand? #find line of best fit a, b = np.
