I am trying to have students working through making a scatter plot based on student predictions and reality. The prediction will be the y value, the true value will be the x value. How can I do this?
One way is to use the full screen graph.
Type “table” and then enter your x and y values. You can have Desmos automatically zoom to fit the data by click the “zoom fit” button at the bottom of the table. You can rename the x and y axis using the graph settings in the upper right corner.
type: y_{1}\sim mx_{1}+b under the table to get regression data.
