Write a system of inequalities to represent the shades portion of the graph.

Answer is

y ≥ 1/3x

y > -x + 4

both lines intersect each other at point (3, 1)

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.
