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(5, 3), M(5, 5), N(2, 5)

a) We can plot the given points and join the consecutive points as follows:

From the graph, we can observe that points A, B, C, and D lie on the same line.

b) We can plot the given points and join the consecutive points as follows:

Therefore, point P, Q, R and S lie on the same line.

c) We can plot the given points and join the consecutive points as follows:

Therefore, points K, L, M and N do not lie on the same line.
