Question

Which of the following ordered pairs does not lie on the $Y$-axis?

• A. $(0,-2)$
• B. $(0,2)$
• C. The point that is 2 units above $(2,-2)$
• D. The point that is 2 units to the right of $(-2,-4)$

Answer 1

The correct option is C The point that is 2 units above $(2,-2)$

A point that lies on the $Y$-axis has its
$x$-coordinate as zero.

$\therefore A=(0,2)$ and $B=(0,-2)$ lie on the $Y$-axis.

The point that is 2 units to the right of $(-2,-4)$ is $C=(0,-4)$, and it lies on the $Y$-axis.

The point that is 2 units above $(2,-2)$ is $D=(2,0)$, and it does not lie on the $Y$-axis. It lies on the $x$-axis.


Thus, the only point among the given options that does not lie on the $Y$-axis is the one that is 2 units above $(2,-2).$
