Answer 1

-2-5*4 = -22 which is not greater than -7
4-5*5 = -21 which is not greater than -7
3-5*(-8) = 43 which is greater than -7
3*3+4*(-8) = -23 which is less than -8
-1-5(-1) = 4 which is greater than -7
3(-1) + 4(-1) = -7 which is not less than -8
so only the third answer is correct.

Answer 2

3,-8
