To find our solution, we first write the equation in the following form:
In this formula a represents the slope, therefore:
Because the line passes through the point P(5, -7), we can fill in the coordinates of this point in the formula and we get the following:
Now, add up 1 to both sides and we get
So the formula will be:
Bringing x to the other sides gives us:
Finally we multiply by 5 to get our standard form (and therefore our final answer):
Hence, the answer is D.
