All the answer choices are in the form of: $\sf\Large (x,y)$

so each number corresponds to the x or the y. Plug those numbers into $\sf\Large y=7x$

thesmartone · Answer

For example, I'll do A for you.

$\sf\Large (42,7)$
$\sf\Large (x,y)$

Which means that
$\sf\Large x=42$
$\sf\Large y= 7$

Plug it in:

$\sf\Large y=7x$

$\sf\Large 7 = 7(42)$

$\sf\Large 7\neq 294$

So that means A is not the answer.
