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.
(– 2, 4): x is negative and y is positive. So, it lies in 2nd quadrant.
(3, – 1): x is positive and y is negative. So, it lies in 4th quadrant.
(– 1, 0): x is negative and y is zero. So, it lies on negative X – Axis.
(1, 2): x is positive and y is positive. So, it lies in 1st quadrant.
(– 3, – 5): x is negative and y is negative. So, it lies in 3rd quadrant.
All of these points are shown in the figure below:
