Which graph shows the equation v = 4 + 2t, where v is the total volume of water in a bucket and t is the elapsed time in minutes?

on a coordinate plane, the x-axis shows elapsed time in minutes (t) and the y-axis shows total volume of water (v). a straight line with a positive slope begins at point (0, 3) and ends at point (5.5, 24).
on a coordinate plane, the x-axis shows elapsed time in minutes (t) and the y-axis shows total volume of water (v). solid circles are at points (0, 3), (1, 6), (2, 10), (3, 14), (4, 18), (5, 22).
