We know that anything that is "independent" is not affected by other "dependent" forces. In math relationships (and algebra, in particular), one variable (the independent one) is thought to drive the behavior of the other one (the dependent one). This tutorial explores that relationship and how it can be expressed and interpreted. Common Core Standards: 6.EE.C.9
