# Plot the points A (1, –1) and B (4, 5)

(i) Draw a line segment joining these points. Write the coordinates of a point on this line segment between the points A and B.

(ii) Extend this line segment and write the coordinates of a point on this line which lies outside the line segment AB.

Answer :

(i)

The points which lie on the line segment AB are C and D.

C(2, 1) and D(3, 3).

(ii)

The points lying on the line outside AB are E and F.

E(0, -3) and F(-1, -5).
