Graphing linear regression

WebGraphing the regression line. When Prism performs simple linear regression, it automatically superimposes the line on the graph. If you need to create additional graphs, or change which line is plotted on which graph, keep in mind that the line generated by linear regression is seen by Prism as a data set. You can add lines to a graph or remove lines … WebApr 23, 2024 · The equation for the regression line is usually expressed as Y ^ = a + b X, where a is the Y intercept and b is the slope. Once you know a and b, you can use this equation to predict the value of Y for a given value of X. For example, the equation for the heart rate-speed experiment is rate = 63.357 + 3.749 × speed.
