Answer:

b - f(x) = x - 1

Step-by-step explanation:

Your slope is represented in front of the x-value in a slope-intercept form equation, which in this case needs to be one. The slope is the change in y over change in x values, but when the change is the same the slope will be one. This is why b is the correct answer because your slope is one, but because it is one you don't need to write down one in front of the x (anything times one will be equal to itself).
