The rule would be addition. (+300)
How is it possible to know how much he started with? Or is it not asking for an exact amount?
I can't see it well sorry
Let's start by tidying up that equation and put it into slope-intercept form (y = mx + b); from there, we can plug in coordinates.

Let's use the distributive property on the right side:

Now add 4 to both sides

Which simplifies to:

Since that's the equation of our line, now we can plug in coordinates and see what it churns out.
We know that the x-coordinate of P = 4 so let's substitute 4 in for x and calculate the y-coordinate:



So the y-coordinate for point P =
10
