which ordered pair is not in the solution set of y>2x+1?

1: (1,4)
2: (3,8)
3: (1,6)
4: (2,5)

To determine which ordered pair is not in the solution set of y > 2x + 1, we need to check each pair and see if it satisfies the given inequality.

The given inequality is y > 2x + 1.

Let's check each option:

1. For the ordered pair (1, 4), substitute x = 1 and y = 4 into the inequality:
4 > 2(1) + 1
4 > 2 + 1
4 > 3
This inequality is true, so (1, 4) is in the solution set.

2. For the ordered pair (3, 8), substitute x = 3 and y = 8 into the inequality:
8 > 2(3) + 1
8 > 6 + 1
8 > 7
This inequality is true, so (3, 8) is in the solution set.

3. For the ordered pair (1, 6), substitute x = 1 and y = 6 into the inequality:
6 > 2(1) + 1
6 > 2 + 1
6 > 3
This inequality is true, so (1, 6) is in the solution set.

4. For the ordered pair (2, 5), substitute x = 2 and y = 5 into the inequality:
5 > 2(2) + 1
5 > 4 + 1
5 > 5
This inequality is false, so (2, 5) is not in the solution set.

Therefore, the ordered pair that is not in the solution set of y > 2x + 1 is (2, 5).
