Answer:
A. (1, -2)
Step-by-step explanation:
We can substitute the variables of x and y into the inequality of
.
Let's start with A, -2 being y and 1 being x.

The absolute value of 1 is 1, and negating that gets us -1.

Indeed, -2 is less than -1! So A is a solution to the inequality.
Let's test the rest of them, just in case.
For B:

Absolute value of 1 is 1, negating it is -1.

-1 is EQUAL to -1, not less than it, so is not a solution to the inequality.
Let's try C.

Absolute value of 1 is 1, negating it is -1.

0 is GREATER than -1, so that is not a solution to the inequality.
Hope this helped!
