Which graph has a rate of change equal to one-third in the interval between 0 and 3 on the x-axis?

On a coordinate plane, solid circles appear on a straight line with a positive slope at (negative 3, 0), (negative 1.5, 1), (0, 2), (1.5, 3), (3, 4).
On coordinate plane, a parabola opens up. Solid circles appear on the parabola (negative 6, 6), (negative 4.5, 2.25), (negative 3, 0), (negative 1.5, negative 0.75), (0, 0), (1.5, 2.25), (3, 6)

On a coordinate plane, solid circles appear on a straight line with a positive slope at (negative 3, 0).5, (negative 1.5, 1), (0, 1.5), (1.5, 2), (3, 2.5).

On a coordinate plane, a curved line opens up and right in quadrants 1 and 2. It goes through (negative 2.25, 11), crosses the y-axis at (0, 1), and is asymptotic to the positive x-axis. Solid circles appear on the line at (negative 2, 9), (negative 1, 3), (0, 1), and (3, 0).
