1.Plot the following points on a graph sheet. Verify if they lie on a line.

(a) A (4, 0), B(4, 2), C(4, 6), D(4, 2.5)

(b) P(1, 1), Q(2, 2), R(3, 3), S(4, 4)

(c) K(2, 3), L(6, 3), M(5, 5), N (2, 5)

Yes, all the coordinate points lie on a line

Yes, all the coordinate points lie on a line.

No, the coordinate points do not lie on a line.
