Nov 12, 2018 · Using the online graphing calculator Desmos, we will learn calculate a line of best fit using a linear regression. To try it yourself, visit: https://www.desmos.com/calculator

First, let’s quickly go over doing a line of best fit in Desmos. This can be done by adding a table, filling in the x and y -data, and then by typing in a general formula for a line.

To find the line of best fit in Desmos, load your data in a table and create an expression approximating the dependent variable as a function of the independent variable.

Graph functions, plot points, visualize algebraic equations, add sliders, animate graphs, and more.

In this activity, students visualize a line to fit a data set, then graph that line with sliders, and use it to make a prediction. Teachers can use the final screen to introduce the concept of the residual.

Creating a line of best fit and then writing equations for the line in slope-intercept form.

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. Write down your equation of …

Jan 21, 2025 · Regression templates allow you to model curves to best fit your graph from a built in list of options. To edit the model, try viewing the model source and exporting it to the expression list or creating a standalone regression model directly in an expression line.
