Question

Which one of the following options represents ordered pairs that have a relationship between x and y coordinates?

Answer 1

$\text{Option A:}$

$x$	Relation	$y$
$2$	$y=2x$	$2\times 2=4$
$4$	$y=2x$	$4\times 2=8$
$6$	Not related	$13$

As all the ordered pairs do not have the $x$ and $y$ coordinates related, option A is incorrect.

$\text{Option B:}$

$x$	Relation	$y$
$2$	$y=3x$	$2\times 3=6$
$3$	$y=3x$	$3\times 3=9$
$4$	$y=3x$	$12$

As all the ordered pairs have a relationship between $x$ and $y$ coordinates, option B is correct.

$\text{Option C:}$

$x$	Relation	$y$
$1$	$y=2x$	$1\times 2=2$
$2$	Not related	$3$
$2$	$y=2x$	$2\times 2=4$

As all the ordered pairs do not have the $x$ and $y$ coordinates related, option C is incorrect.

$\text{Option D:}$

$x$	Relation	$y$
$2$	$y=½\left(x\right)$	$1$
$2$	Not related	$3$
$3$	Not related	$3$

As all the ordered pairs do not have the $x$ and $y$ coordinates related, option D is incorrect.
