Learning goals: Teacher Facing Coordinate (orally and in writing) tables, graphs, and equations that represent the same proportional relationship. Interpret two different graphs that represent the same proportional relationship, but have reversed which quantity is represented on each axis. Write an equation to represent a proportional relationship given only one pair of values or one point on the graph.
