NettetFor your line, pick two convenient points and use them to find the slope of the line. Find the y -intercept of the line by extending your line so it crosses the y -axis. Using the slopes and the y -intercepts, write your equation of "best fit." Do you think everyone will have the same equation? Why or why not? Nettet10. nov. 2014 · Without going into much detail, polyfit will determine the line of best fit that will minimize the sum of squared errors between the best fit line and your data points. Therefore, this slope will give you the best rate at which distance is increasing per year, given your point distribution. simplebake download

Substituting a = 0.458 and b = 1.52 into the equation y = ax + b … Nettet15. okt. 2024 · 3 Answers Sorted by: 1 You can use numpy's least square We can rewrite the line equation y=mx+c as y = Ap, where A = [ [x 1]] and p = [ [m], [c]]. Then use lstsq to solve for p, so we need to create A by adding a column of ones to df import numpy as np df ['ones']=1 A = df [ ['strike','ones']] y = df ['IV'] m, c = np.linalg.lstsq (A,y) [0] raves hawaii
