Graph the line that represents a proportional relationship between d and t with the property that 6 units in t corresponds to an increase of 7 units in d.
What is the unit rate of change of d with respect to t? (That is, a change of 1 unit in t will corres
change of how many units in d?)
The unit rate of change is
