Answer
1. - x < -y
Step by step explanation
When we multiply, add and divide the value remains the same.
But when you change the sign, the inequality direction will be > in this case, otherwise that is not ture.
For instance,
2 < 3
-2 < -3 is not true.
Because -2 is greater than -3
Hope this will help you.

1 2 3 4 5 6 7 8 9
