Plotting Function Tables in Desmos or GeoGebra

Use a graphing tool to connect a table of values with its graph. In Desmos, open a table and enter x values in the first column and y values in the second. Add a rule such as y = 3x – 2 in the next line. The graph will show both the plotted points and the line, making agreement easy to see. In GeoGebra, use the Table tool or spreadsheet view, enter the pairs, then create a function and plot it. Check for a point that does not lie on the curve and revisit your arithmetic. Change the rule slightly and observe how the graph shifts or tilts. Export a screenshot for your notes and label the axes. Use the trace feature to read coordinates at chosen inputs. Compare table values with the graph to build intuition about slope and intercept. Save your file so you can revisit and extend the investigation later.
