What does a point represent

A point is the most fundamental object in geometry. It is represented by a dot and named by a capital letter. A point represents position only; it has zero size (that is, zero length, zero width, and zero height).

Step-by-step explanation:

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
