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: 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.

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.

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.

Write a linear equation to describe the given model. Step 1: Find the slope. This line goes through ( 0, 40) and ( 10, 35) , so the slope is 35 − 40 10 − 0 = − 1 2 . Step 2: Find the y -intercept. We can see that the line passes through ( 0, 40) , so the y -intercept is 40 . Step 3: Write the equation in y = m x + b form.
