A disc is thrown into the air with an upward velocity of 18 feet per second. Its height, h
in feet after
t
seconds is given by the function

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? )
