Question

Jackie claims that points with the same xx- and yy-coordinates must lie in Quadrant I or Quadrant III. Do you agree or disagree? Explain your answer.

Answer 1

True.

Explanation:

This statement is true because if a point has the same x and y coordinates it means that they have the same sign, and the only quadrants where both coordinates have the same sign are Quadrant I and Quadrant III, since for Quadrant I both are positive and for Quadrant III both are negative. For the other Quadrants the x and y coordinates cannot be the same because their sign are necessarily different.
