How to get line of best fit on desmos
This measures the strength of the linear correlation between two data sets, so Desmos will display it in the special case that your model is linear and contains both slope and intercept parameters (e.g., \(y_1 \sim mx_1 + b\)). The coefficient of determination (\(R^{2}\)). This measures your regression model’s “goodness of fit.”You can add an open point manually. Use a table to determine where your point of discontinuity is. Then graph the point on a separate expression line. To change the point from a closed circle to an open circle, click and long-hold the color icon next to the expression. The style menu will appear.
