1. In which quadrant or on which axis do each of the points (- 2, 4), (3, – 1), (- 1, 0), (1, 2) and (- 3, – 5) lie? Verify your answer by locating them on the Cartesian plane.

Ans. We need to determine the quadrant or axis of the points (– 2, 4), (3, – 1), (- 1, 0), (1, 2) and (– 3, – 5).

First, we need to plot the points (– 2, 4), (3, – 1), (- 1, 0), (1, 2) and (– 3, – 5) on the graph, to get

We need to determine the quadrant, in which the points (– 2, 4), (3, – 1), (- 1, 0), (1, 2) and (– 3, – 5) lie.

From the figure, we can conclude that the point (– 2, 4) lie in II^nd quadrant.

From the figure, we can conclude that the point (3, – 1) lie in IV^th quadrant.

From the figure, we can conclude that the point (–1, 0) lie on x-axis.

From the figure, we can conclude that the point (1, 2) lie in I^st quadrant.

From the figure, we can conclude that the point (– 3, – 5) lie in III^rd quadrant.
