So, the equation of the line of best fit for a given data is b = y - mx Find the y-intercept of the line using the formula: Find the slope of the best fit line using the formula:ģ. Calculate the mean of x values and y values (X and Y)Ģ. Statisticians generally use the least-squares method to find the equation of the best fit line. The least-square method is a more accurate way of finding the line of best fit. Step 3: Click on "Reset" to clear the field and enter new data points.Step 2: Click on the "Calculate" button to find the best fit.Step 1: Enter the data points (x, y) in the space provided.NOTE: Each pair should be enclosed in a bracket separated by a commaįollow the steps given below to use the calculator: of a Straight Line Test Yourself Straight Line Graph Calculator.
