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

Answer 1

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.
