Question

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

Answer 1

Any good answers will get medals. If you can just explain how to do it I can find the answer myself too.

Answer 2

right down a few coordinates with opposite signs. (-x, y), (x, -y). I think you will see what they are getting at.

Answer 3

Any point is in the form (x,y)


If x is positive then y is negative (since "The coordinates of an ordered pair have opposite signs"). This would mean that the point is in the fourth quadrant.

OR

If x is negative, then y is positive. So this point would be in the second quadrant.
