Being able to recite the slope formula is not good enough. During this session we will examine concepts of rate, unit rate, and the constant of proportionality as they relate to slope—specifically, that the slope of a proportional relationship is equal to the unit rate. Further, we will model how to use similar triangles to derive the slope formula.
