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.

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
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.

Points rise diagonally in a narrow scatter between (0, 1) and (9, 9). A line labeled A is constant and horizontal extending from (0, 7) through (10, 7). A line labeled B increases diagonally extending from (0, 1) through (9, 9). A line labeled C decreases diagonally extending from (0, 8) through (4, 2). All values are estimated. lesoutrali bot
