The coordinates of an ordered pair have opposite signs. In which quadrant(s) must the ordered pair lie? Explain..
1 answer
An ordered pair with opposite signs must lie in either the second or fourth quadrant. This is because in the second quadrant, the x-coordinate is negative and the y-coordinate is positive. In the fourth quadrant, the x-coordinate is positive and the y-coordinate is negative. Since opposite signs indicate one positive and one negative value, the pair must lie in one of these two quadrants.
