  2. Plot the following points (2, 0), (–5, 0), (3, 0), (–1, 0) in the Cartesian plane. Where do they lie?

  3. Plot the points (–4, 3),(–3, 3),(–1, 3),(0, 3),(3, 3) in the Cartesian Plane. What can you say about the position of these points?

  4. Plot the following points A(2, 2), B(–2, 2), C(–2, –1), D(2, –1) in the Cartesian plane. Discuss the type of the diagram by joining all the points taken in order

  5. If the distance between the points (5,–2), (1, a), is 5 units, find the values of a.

  6. Let A(2, 2), B(8, –4) be two given points in a plane. If a point P lies on the X- axis (in positive side), and divides AB in the ratio 1: 2, then find the coordinates of P.
