The coordinates have opposite signs. Which choice includes all the quadrants that could contain the point?

Final answer:

A point with coordinates that have opposite signs could lie in either the second or fourth quadrant of a coordinate system. The second quadrant contains points where x is negative and y is positive, while the fourth quadrant contains points where x is positive and y is negative.

Explanation:

When discussing the coordinates with opposite signs in a coordinate system, we are referring to the locations where the x and y coordinates have different signs. In this case, we are considering which quadrants could contain a point with coordinates that have opposite signs. To visualize this, we must remember that the coordinate system is divided into four quadrants, with each axis serving as a boundary between them. The quadrants are usually numbered counterclockwise, starting with the top right quadrant as the first quadrant.

In the first (I) quadrant, both x and y are positive. In the second (II) quadrant, x is negative while y is positive. In the third (III) quadrant, both x and y are negative. And in the fourth (IV) quadrant, x is positive while y is negative. Therefore, if a point has coordinates with opposite signs, it could only be found in the second (II) and fourth (IV) quadrants, where one of the coordinates is positive and the other is negative.
