Answer:
the desired equation is
y = (1/3)x - 2.
Explanation:
Note that the given line has a slope of 1/3. A new line parallel to the given line will also have the slope 1/3. The new line goes through the point (3, -1).
Start with the equation y = mx + b. Let y = -1, x = 3, m = 1/3.
Then: -1 = (1/3)(3) + b, or b = -2.
Then the desired equation is
y = (1/3)x - 2.
