A teacher writes the following six ordered pairs on the board:
(−6,2),(4,0),(−9,−7),(0,−8),(7,−1),(−3,0).
(i) Copy the list and beside each pair write the name of the quadrant or axis where the point is located.
(ii) Without plotting, determine which of the given points have the same ordinate sign but different abscissa signs. Explain how you identified them.
(iii) If another point E(x,y) has the same abscissa sign as (−9,−7) and the same ordinate sign as (7,−1), in which quadrant will E lie? Justify your answer.
