Match My Line (Direct Variation)

In Ontario our grade 9 students describe linear relationships as direct or partial variations. Our grade 9 applied students are supposed to look at linear relationships only if they are in context. This activity investigates direct variations in the context of a distance time graph. For the follow up investigation of partial variations, see here https://teacher.desmos.com/activitybuilder/custom/55dc9768265fda125f2847d5 Note that you may want to change the title so that the phrase direct variations does not appear so it does not give away the topic. This was inspired by Michael Fenton's Match My Line which is awesome. Check it out here https://teacher.desmos.com/activitybuilder/custom/5605bb5f00701ed10fb09314
