To determine if (-1, 7) is a solution to the system of inequalities, we need to check if it satisfies both inequalities.

1. For the inequality 2x + 5y > -6:

Substitute the coordinates (-1, 7):

2(-1) + 5(7) > -6

-2 + 35 > -6

33 > -6

This inequality is true, so (-1, 7) is a solution to the first inequality.

2. For the inequality 4x + 3y ≤ 2:

Substitute the coordinates (-1, 7):

4(-1) + 3(7) ≤ 2

-4 + 21 ≤ 2

17 ≤ 2

This inequality is not true. So, (-1, 7) is not a solution to the second inequality.

Since (-1, 7) does not satisfy both inequalities in the system, the answer is:

B. No
