Question
Points (1, – 1), (2, – 2), (4, – 5), (– 3, – 4) ______.
Options
lie in II quadrant
lie in III quadrant
lie in IV quadrant
do not lie in the same quadrant
Solution
Points (1, – 1), (2, – 2), (4, – 5), (– 3, – 4) do not lie in the same quadrant.
Explanation:
In points (1, – 1), (2, – 2), (4, – 5) x-coordinate is positive and y-coordinate is negative.
So, they all lie in IV quadrant.
In point (– 3, – 4) x-coordinate is negative and y-coordinate is negative.
So, it lies in III quadrant So, given points do not lie in the same quadrant.
