WebJan 10, 2015 · Intuitively, if you were to draw a line of best fit through a scatterplot, the steeper it is, the further your slope is from zero. So the correlation coefficient and regression slope MUST have the same sign (+ or -), but will not have the same value. For simplicity, this answer assumes simple linear regression. Share Cite Improve this answer … WebOct 6, 2024 · 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 = 0.458x + 1.52 We can superimpose the plot of the line of best fit on our data set in two easy steps. canbus fejlfinding

How do I calculate the gradient of a best fit line in python? I have 2 arrays x and y that I plotted, and then made a best fit line using polyfit (found an example online). I am now trying to find the gradient of my best fit line but I am unsure how. I have tried looking at similar questions on here but nothing I have tried so far has worked.
