The coordinates of an ordered pair have opposite signs in which quadrants must the ordered pair lie? explain. (2 points)

II quadrant or IV quadrant

Step-by-step explanation:

we know that

In the I quadrant

The x-coordinate and the y-coordinate are both positive

In the II quadrant

The x-coordinate is negative and the y-coordinate is positive

In the III quadrant

The x-coordinate and the y-coordinate are both negative

In the IV quadrant

The x-coordinate is positive and the y-coordinate is negative

therefore

If the coordinates of an ordered pair have opposite signs, then the ordered pair must lie in the II quadrant or in the IV quadrant

where are the choices?

answer: all of the odd numbers were opened

the first person was the one that was opening all of the lockers. since one is odd, this causes all of the odd number lockers to be opened in the end.
