# Share two additional values of 'x' with them. Ask them to locate these on the line created, using the 'point on object' function in Geogebra. This will give them the 'y' value corresponding to the 'x' values given.

# Students should identify additional points on the line in Geogebra and confirm that these also satisfy the equation
# Students should identify additional points on the line in Geogebra and confirm that these also satisfy the equation
# Students calculate additional values of 'x' and 'y' in the linear equation given. They plot these additional points on Geogebra and confirm that these lie on the created line.
