To create statistical graphs on Desmos Calculator[https://desmoscalculator.net/matrix-calculator/], begin by entering a table of data using the table feature. You can type in your x-values and y-values manually, or paste data directly into the table. Once the data is entered, the calculator automatically plots the points on the graph. From there, you can add a regression line or curve by typing an equation that fits the pattern, such as y1 ~ mx1 + b for linear regression. The calculator will instantly generate the best-fit line and give you the values of the slope, intercept, and correlation.
