Graph the line that represents a proportional relationship between ddd and ttt with the property that an increase of 333 units in ttt corresponds to an increase of 444 units in ddd. What is the unit rate of change of ddd with respect to ttt? (That is, a change of 111 unit in ttt will correspond to a change of how many units in ddd?) The unit rate is . Graph the relationship.
