Nine Points, Three Lines

In this activity, students will practice constructing linear equations and also learn properties of collinearity – when the same line passes through more than one point. This activity is based on the work of Don Steward: http://donsteward.blogspot.com/2013/11/4-in-line-further-extended.html French translation courtesy of Jocelyn Dagenais: https://teacher.desmos.com/activitybuilder/custom/5b06f51817136852e135bf2c
