Students will be identifying the independent and dependent quantities when given a table or graph. Tables make it a little easier to identify these two quantities, but on a graph, this is more difficult. It is important to note that the independent quantity is noted by the x-axis. This is the starting point when graphing, so it makes sense that the independent quantity would be located here. The dependent quantity is shown on the y-axis. It is best when practicing that student practice with tables and graphs demonstrating the same scenario simultaneously. This helps ensure they are making connections between the two representations.

6.6 Expressions, equations, and relationships. The student applies mathematical process standards to use multiple representations to describe algebraic relationships. The student is expected to:
(B) write an equation that represents the relationship between independent and dependent quantities from a table
