Final answer:
The equation y = 1/3x - 4 represents a line with a slope of 1/3 and a y-intercept of -4.
Step-by-step explanation:
The equation given is y = 1/3x - 4, with m = 1/3 and b = -4. The value of m, which is 1/3, represents the slope of the line. This means that for every increase of 1 unit in the x-coordinate, the y-coordinate increases by 1/3. The value of b, which is -4, represents the y-intercept.
This is the point where the line crosses the y-axis when the x-coordinate is 0. In this case, the line intersects the y-axis at -4.
