Question

Plot the following points on a graph sheet and 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) $K(2,3),L(5,3),M(5,5),N(2,5)$

Answer 1

$\left(a\right)$ The points $A,B,C,D$ are plotted on the graph.

From the figure, we can observe they are in a straight line.

$\left(b\right)$ The points $P,Q,R,S$ are plotted on the graph.

From the figure, we can observe they are in a straight line passing through the origin.

$\left(C\right)$ The points $K,L,M,N$ are plotted on the graph.

From the figure, we can observe they are not in a straight line.
