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.

Estimating the line of best fit exercise Google Classroom About Transcript The line of best fit is a line that shows the pattern of data points. If we can find a good line, it means there is a linear trend. If not, it means there is no linear trend. We can’t ignore points that don’t fit the trend. Created by Sal Khan. Questions Tips & Thanks

Line of Best Fit (Least Square Method) – Varsity Tutors
A more accurate way of finding the line of best fit is the least square method . Use the following steps to find the equation of line of best fit for a set of ordered pairs (x1,y1),(x2,y2), …(xn,yn) ( x 1, y 1), ( x 2, y 2), … ( x n, y n) . Step 1: Calculate the mean of the x x -values and the mean of the y y -values.
