Consider the two points a(9.7) and b(5,2).
what is the ratio of the vertical change from a to b to the horizontal change from a to b? in other words, what is the
slope?
what the answer

Graph the line that represents a proportional relationship between d and t with the property that an increase of 33 units in t corresponds to an increase of 44 units in d. what is the unit rate of change of dd with respect to t? (that is, a change of 11 unit in t will correspond to a change of how many units in d? )
