Final answer:
The equation of the line with a slope of 1/3 and a y-intercept of -1 is y = (1/3)x - 1.
Step-by-step explanation:
To find the equation of a line with a given slope and y-intercept, we can use the slope-intercept form of a linear equation, which is y = mx + b.
In this case, the slope is 1/3 and the y-intercept is -1. Plugging these values into the slope-intercept form, we get y = (1/3)x - 1.
Therefore, the correct equation of the line is y = (1/3)x - 1.
