Graph the line that represents a proportional relationship between d and t with the property that an
increase of 5 units in t corresponds to an increase of 8 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 correspond to a
change of how many units in d?)
The unit rate is
Graph the relationship.
