Question

Plot the following points on a graph sheet. Which points lie on a line ?
$\left(a\right)A(4,0),B(4,2),C(4,6),D(4,2.5)$
$\left(b\right)P(1,1),Q(2,2),R(3,3),S(4,4)$
$\left(c\right)K(2,3),L(5,3),M(5,5),N(2,5)$

• A. Points in $\left(a\right)$
• B. Points in $\left(b\right)$
• C. Points in $\left(c\right)$
• D. All of these

Answer 1

Answer: (A), (B)

The correct options are
A Points in $\left(a\right)$
B Points in $\left(b\right)$

In the above graph, the points $A,B,C,D$ which are represented in red colour lie on a straight line.

Similarly, the points $P,Q,R,S$ which are represented in black colour lie on a straight line.

But, the points $K,L,M,N$ which are represented in blue colour doesn't lie on a straight line.
