Explanation:
The slope of the line is equal to the coefficient of x, which is 1/3. The best way to remember how to do slope is to memorize "rise over run". In this case, the "rise" of the slope is 1 and the "run" is 3. This means that for every 3 steps in the x-direction, there is one step up in the y-direction.
Now, we look at the shift. Since the shift is +5, we move the line up 5 in the positive y-direction so that the y-intercept becomes (0,5). You can check this mathematically by plugging in 0 for x:
