Final answer:
The equation of the next parallel line is y = 1/3x + 2.
Step-by-step explanation:
To find the equation of the next parallel line, we need to calculate its slope. Since the lines are parallel, they will have the same slope. The first line has a slope of 1/3. The next line needs to cross the y-axis at 2, which means the y-intercept is 2. Therefore, the equation of the next parallel line is y = 1/3x + 2 (Option a).
