I ask for (b) not (a)
X < -8
X smaller than -8, answer x= -9.
-9 is smaller than -8.
-9 -8 -7 -6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6 7 8
Number to the right is bigger.
Number to the left is smaller.
Answer should be = -9.
Please ask your teacher.

The correct answer for part b) is -9. The person who created the worksheet entered the wrong answer of -7
