Question

The coordinates of an ordered pair have opposite signs. In which quadrant(s) must the ordered pair lie? Explain.

Answer 1

The ordered pair must lie in either quadrant II or quadrant IV. This is because the x-coordinate and y-coordinate of the ordered pair have opposite signs, which means that one coordinate must be negative and the other must be positive. Quadrant II has both negative x- and y-coordinates, while quadrant IV has both positive x- and y-coordinates.
