See explanation below
Step-by-step explanation:
We pick points from the given table to graph the line:
point (t, V) = (0, 0), (1, 15), (2, 30), (3, 45), (4, 60) and (5, 75)
Where t (time) will be on the horizontal axis
V (volume) will be the on the vertical axis
Plotting the graph:
Graph of the first one could not contain all the points stated above, so I did another graph that include all points on the table.
