What are the following ordered pairs? ?

The ordered pairs for A, C and E all work in these inequalities. 

In order to find this, you need to test them all and see if they work for both. 

Ordered Pair #1: (-1, 10)

2x < y
2(-1) < 10
-2<10 (TRUE)

y > 7
10 > 7 (TRUE)

Ordered Pair #2: (1, 9)

2x < y
2(1) < 9
2 < 9 (TRUE)

y > 7  
9 > 7 (TRUE)

Ordered Pair #3: (17, 50)

2x < y
2(17) < 50
34 < 50 (TRUE)

y > 7 
50 > 7 (TRUE)

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.
