a) The elephant eats 400 pounds of vegetation each day, therefore to find the total amount v it has eaten after a certain number of days d, just multiply 400 by d:
v = 400d
b) Plug in different values of d to find v:
For d = 1, v = 400(1) = 400
For d = 2, v = 400(2) = 800
For d = 3, v = 400(3) = 1200
c) The ordered pairs to graph are (d, v) for various values of d, for example:
(0, 0), (1, 400), (2, 800), (3, 1200)
