Answer:
I believe that you would shade the one in the bottom right corner, but you might want to double check
Step-by-step explanation:
you take a (x,y) coordinate from each quadrant and plug in the numbers to see if the equation is correct. If it isn't, you do not shade that quadrant.
so for example, y<1/2 x
say your coordinate is (2,1)
you plug in the numbers so that it looks like 1>1/2×2.
1/2 × 2 is 1,
so therefore this equation is incorrect because 1 is not greater than one.
Your answer is 8,000 minus 6 & 4
