**Exercise 3.3**

**Q.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.

**Solution:**

(-2, 4) → Second quadrant

(3, -1) → Fourth quadrant

(-1, 0) → x-axis

(1, 2) → First quadrant

(-3, -5) → Third quadrant

**Q.2.** Plot the points (x, y) given in the following table on the plane, choosing suitable units of distance on the axes.

**Solution:**

Taking 1 unit = 1 cm, the points (x,y) on the plane are plotted below.
