Question

Which of the given points lie on $y$-axis?
$A(1,1),B(1,0),C(0,1),D(0,0),E(0,1),F(1,0),G(0,5),H(7,0),I(3,3)$.

• A. $B,D,F,H$
• B. $A,C,E,H$
• C. $C,D,E,G$
• D. $B,D,F,G$

Answer 1

The correct option is C $C,D,E,G$

If a point is on $y$-axis , then the $x$ co-ordinate of that point should be zero.

Here, the $x$-coordinate is zero at:

$C(0,1)$,

$D(0,0)$,

$E(0,1)$

and $G(0,5)$.

Therefore, these points lies on the $y$-axis.

Hence, option $C$ is correct.
