What is a proportional relationship? What are some key elements of a proportional relationship? What does it appear as on a graph, in an equation, or on a table?
A proportional relationship is a constant pattern comparing two things, such as cost per pound. Proportional relationships always make a straight line through (0,0) and have an equation like y=kx, where "k" is the pattern number. In a table, when you multiply X by the constant (k, the pattern) you get Y.
