Question
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)
Solution
In each case we draw the x-axis and the y-axis and plot the given point.
(a) on plotting the points A(4, 0), B(4, 2), C(4, 6) and D(4, 2.5) and then joining them we find that they all lie on the same line.
(b) On plotting the points P(1, 1), Q(2, 2), R(3, 3) and S(4, 4) and then joining them we find that they all lie on the same line.
(c) Plotting the points k(2, 3) L(5, 3), M(5, 5) and N(2, 5) and joining them we find that all of them do not lie on the same line.
