Graph functions, plot points, visualize algebraic equations, add sliders, animate graphs, and more.This video shows how to generate a best fit line equation using desmos.comA line of best fit, also called a trend line or linear regression, is a straight line drawn on a graph that best represents the data on a plot. This line passes through some of the points, all of the points, or none of the points. It can be used to make predictions or to show trends in data.8.SP.2 Understand that straight lines are widely used to model relationships between two quantitative variables. For scatter plots that suggest a linear association, informally fit a straight line, and informally assess the model fit by judging the closeness of the data points to the line. (GAISE Model, steps 3 and 4)EXPLORE: In the example below: Drag the BLUE points. Drag along the line. Drag the grid. Click the arrow in front of "Line" in step 3 to view how this is created! Moveable Line.In the same cell as the equation, Desmos will display the values of slope and intercept, along with the correlation coefficient (R 2 value) for the best fit line. R 2 is a measure of how well the line of best fit matches the data; the closer it is to 1, the better the fit is. The line of best fit will automatically appear on your graph.The equation with the "r2" value closest to ± 1 is the best fit for the data. 5. To see the equation along with the scatter plot Y = (put in the equation you obtained in step 4), then GRAPH Examples - answer the three questions below for questions 1 - 4. a. Graph the data in the table below. b.To have Desmos calculate your R 2 value in a new input line type y1 ~ a (x1-h)^2+k. Desmos uses y 1 to represent the y-value in a data table and x 1 to represent the x-values in a table. Adjust your sliders until you get the highest possible value for R².

Thus, the residual for this data point is 62 - 63.7985 = -1.7985.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.”This activity explores drawing lines of best fit.
