The residual plot with a line of best fit that is a good model is the option third residual plot.
Which line of best fit is a good model?
The line of best fit should cut across data points in such a way that the data points on each side are relatively the same number.
A residual plot is a graph which shows the residuals on the y axis and the independent variable on the x axis.
The goodness of fit of a linear model is depicted by the pattern of the graph of a residual plot. If each individual residual is independent of each other, they create a random pattern together.
The data points on both sides should also be a roughly the same distance away from the line.
In the graph 3rd the plots are both on top and on the bottom of the line.
The option third residual plot fits these parameters and so shows the line of best fit as a good model.
