A mathematical procedure for finding the best-fitting curve to a given set of points by minimizing the sum of the squares of the offsets ("the residuals") of the points from the curve. The sum of the squares of the offsets is used instead of the offset absolute values because this allows the residuals to be treated as a ... 3. Calculate the y-intercept (b) using the following formula: b = mean (y) – m * mean (x) 4. Determine your line of best fit using this equation: y = mx + b.

Step 3: Check if the value obtained in step 2 is ...Apr 16, 2020 · Plot the number of the planet (Mercury is. 1 {\displaystyle 1} , etc.) versus the distance. Note that it does not look like a line, and so finding the line of best fit is not fruitful. It does, however look like an exponential curve. Therefore, plot the number of the planet versus the logarithm of the distance. 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.

Using the points ( 0, 100) and ( 13, 0) , the slope of the line of best fit is about: ( 100 − 0) percent ( 0 − 13) hours = 100 percent − 13 hours ≈ − 7.7 percent hour. This means that the battery life remaining decreases by about 7.7. ‍. percent for every additional hour of time spent on phone. The y -intercept is about ( 0, 100) . The first portion of results contains the best fit values of the slope and Y-intercept terms. These parameter estimates build the regression line of best fit.
