3.5: The Line of Best Fit – Mathematics LibreTexts
The equation of the line of best fit is y = ax + b. The slope is a = .458 and the y-intercept is b = 1.52. Substituting a = 0.458 and b = 1.52 into the equation y = ax + b gives us the equation of the line of best fit. [y=0.458 x+1.52 nonumber ] We can superimpose the plot of the line of best fit on our data set in two easy steps.

Line of Best Fit (Least Square Method) – Varsity Tutors
To find the line of best fit, we can use the least squares regression method. However, I’ll show you a simplified version of the method to obtain an approximate line. First, find the means of x and y values: Mean of x = 2 + 3 + 5 + 7 + 9 5 = 26 5 = 5.2. Mean of x = 4 + 5 + 7 + 10 + 15 5 = 41 5 = 8.2.

Line of Best Fit: What it is, How to Find it
Equation for the Line of Best Fit. Our online linear regression calculator will give you an equation to go with your data. For example, the first graph above gives the equation y = 1 + 1x. If you graph this equation on a graphing calculator (such as this one ), you’ll see that the line matches perfectly with the in the first image above.

Computer spreadsheets, statistical software, and many calculators can quickly calculate the best-fit line and create the graphs. The calculations tend to be tedious if done by hand. Instructions to use the TI-83, TI-83+, and TI-84+ calculators to find the best-fit line and create a scatterplot are shown at the end of this section.

Here’s a process you might try. Find the point that is the closest to one corner. Then, find the point that is closest to the opposite corner. Connect those two points. Then, look at the line you draw and compare the rest of the points to it. If there are more points above the line than below it, then you might need to move the up some.

How to Write Best Fit Line Equations – Effortless Math
Step 1: Plot the Data on a Graph. The first step to writing a best-fit line equation is plotting your data on a graph. The x)-axis typically represents the independent variable, while the (y)-axis represents the dependent variable. Once you’ve placed your data points on the scatter plot, you’ll begin to see the shape of the data.
