Web6 de oct. de 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.

Web23 de ene. de 2024 · Observe that the plot is not at all smooth since the underlying data doesn’t follow a smooth line. To plot a smooth curve, we first fit a spline curve to the curve and use the curve to find the y-values for x values separated by an infinitesimally small gap. We can get a smooth curve by plotting those points with a very infinitesimally small gap. saint mary guttenberg iowa
