The value of this expression is 
In order to find this, you divide each term separately. First we'll start with the numbers in the front.

Now that we have the first number, we look to the 10s and the powers they are raised to. Since we are looking at powers of the same number, we can use the properties of exponents to simply subtract the numbers they are raised to.

Then we put the two back together for the final answer.

Answer:
y=1x+2

im not sure if this is correct but i tried my best
I guess the only way to use subtraction is to take the total area of the grid and subtract it by the total area around the figure. So it since it is a 10 by 10 grid, it would be 100 (since 10*10=100) minus the area around the shape.
