For this case we have that by definition, an equation of the line of the slope-intersection form is given by:

Where:
m: It's the slope
b: It is the cut-off point with the y axis
We have two points through which the line passes, then we find the slope:


Then, the equation is of the form:

We substitute a point and find b:

Finally we have:
y = x-4
Answer:
Option B
