=== Objectives ===
Understand how a linear equation is formed
Plot points on a linear equation, on the graphics view in Geogebra
Identify additional points on the line created
=== Estimated Time ===
One period of 45 minutes
=== Prerequisites/Instructions, prior preparations, if any ===
Introduction to linear equation in two variable
=== Materials/ Resources needed ===
Spreadsheet with different combinations of 'x' and 'y'
Geogebra
=== Process (How to do the activity) ===
# Share the spreadsheet containing sets of three 'x' and 'y' values with students. Each team of 2-3 students can get one or two such sets. The team should plot the points representing the 'x' and 'y' values provided, in Geogebra.
# The team should connect the points using the 'Line' function in Geogebra. They should verify that the three points lie on the line created.
# 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 study the line created and identify the general equation of the line in the ax+by+c=0 form.
# Students should identify additional points on the line and confirm that these also satisfy the equation
