Would a point on the boundary line of the graph of the inequality y≥−2x+5 fall in the set of solutions of the inequality?

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.

Basic algebra equation. first set up your equation: divide out 9.and now you are left with 2x + 4 = 8.
