Identifying proportional relationships from graphs (Full video)

Supporting grades: 7

Description: Worked example identifying proportional relationships from graphs. And we have the choices, but let's actually look at the coordinate plane below, to think about how many proportional relationships are depicted here. So you immediately would rule out our green curve, here because this is not a line. You don't have a constant relationship between Y being some proportionality constant times X.
